Product overview To extend the life of concrete buildings, continuing the inspection and implementing renovation and repair appropriately of the buildings is essential. At the same time, the accurate and quick method for the building inspection is required to promote the building maintenance. This product is indispensable for repairing/rebuilding and maintaining reinforced concrete structures using its accurate and speedy diagnostic technology. This product (concrete internal probe device) radiates electromagnetic waves through the surface of concrete and receives reflected signals from objects inside the concrete such as rebars, cavities, or other objects that have different electrical characteristics from concrete. Object position and depth are then displayed and recorded as image data. CAUTION Judge the scan result in consideration of the depth sensing capability of this product. Since the depth sensing capability of this product is subject to the conditions of the object of investigation, judging the scan result with no consideration of the depth sensing capability may cause the accidental cutting of rebars. IMPORTANT NOTE: To comply with FCC & IC RF exposure compliance requirements, the antenna used for this transmitter must be installed to provide a separation distance of at least 20 cm from all persons and must not be co-located or operating in conjunction with any other antenna or transmitter. 1 1.1.

(1) Detect either metallic or non-metallic object. Reflected electromagnetic waves are generated at an interface when the electrical property of an object is different from that of concrete. Thus, this product can probe polyvinyl-chloride pipes and cavities (dependent on the position and size) as well as the rebar. Note that polyvinyl-chloride pipes and cavities echo weakly in compared with the rebar. If a polyvinyl-chloride pipe or cavity is near or below the rebar, the reflected signals from the polyvinyl-chloride pipe or cavity may not be obtained due to the strong reflected signals from the rebar. Thus, care should be taken when you make a judgment on the scan result.
(2) Detect rebars that cross the scanning direction. Rebars that cross the scanning direction make a large magnetic wave reflection. On the other hand, the rebar that is parallel to the scanning direction makes a smaller magnetic wave reflection. Even if scanning is performed above rebars that is parallel to the scanning direction, this product can still detect any rebars that are crosswise to the scanning direction.
(3) Obtain continuous scan results. The scan result are obtained as a representation of the vertical cross section (continuous scan result) of the inside of concrete. Thus, a comprehensive view of the internal concrete conditions can be obtained.
(4) Obtain scan results at the site. This product does not need to be secured to the surface of concrete. Scanning is carried out while this product is moved, and scan results concerning the internal conditions of the concrete can be provided immediately.
(5) Save and recall scan data. The scan data can be saved and recalled to/from an internal memory of Smartphone
(controller). The data saved in Smartphone can also be sent to an external PC by using PC connection function of Smartphone.
(6) Print the scan data without cable connection. The scan data can be printed out to the optional printer via the Bluetooth interface of Smartphone as the controller. 3
(7) Perform real time automatic surface wave processing Internal fixed surface wave data is used to automatically remove the wave reflected from the concrete surface during scanning enabling the showing of the reflected wave from rebars. Furthermore, surface wave processing can be switched to processing that uses scan data surface waves during scanning (real time manual deduction) enabling highly accurate surface processing.
(8) Change sensitivity and perform image processing for scan data after completing the scan. This product can display scan results after changing sensitivity or performing image processing (manual surface wave processing, peak processing, original image, fixed surface wave processing, or deduction processing). Thus, performing a scanning again with a new sensitivity setting is not necessary.
(9) Display the data of an arbitrary point after scanning (scroll function). This product can store the data of 15 m width at a time and display the data of arbitrary points continuously.
(10) Compact and light weight. This product weighs only about 1.0 kg(not including the controller: Smartphone), and it has easy operations.
(11) Operate with the battery pack. This product (sensor unit not including the controller) can operate with the battery pack for about 7 hours (at normal temperature). 4 1.3. Configuration

The continuous operation time for the fully charged battery is approx. 7 hours. The time depends on the operation content. When the continuous operation time is forecasted beyond 7 hours, the preparation of asecond battery is recommended. 29 3.3. Scanning Perform the scan with the following procedure.
(1) Confirm all settings of the product. The settings to be confirmed are [Display mode] (B/BA) , [Measurement mode]
(Distance/Time), [Color] (Absolute /Offset), [Relative permittivity], and [Sensitivity]. For the setting procedure, refer to Section 4 NJJ-200 application functions. When the location of the embedded steel bar is known or the width of concrete is known, perform the depth calibration in accordance with Section 6.1 Relative permittivity setup.
(2) Place this product on the start line. The position to be sensed is the cross point of the line between both side LEDs
(Refer to Figure 1-2 and .) and the line between the front and rear LEDs (Refer to Figure 2-1 and ). Place the sensor unit so as to superpose the line between both side LEDs on the start line (Refer to Figure 3-1) and to superpose the line between the front and rear LEDs on the scanning line (Refer to Figure 3-1).
(3) Start the scan. Tap [Start] icon (Refer to Figure 4-1 ) on the main screen of Smartphone, or press [Start] button (Refer to Figure 1-2 ) on the sensor unit. After one second, a beep sounds and the fix cursor is displayed on B mode screen. Note Caution
The scan is automatically stopped when the sensor unit stays at a position more than 8 seconds.
(4) Move the sensor unit along with the scan line. Make sure the moving speed is less than 40cm/s. If the speed exceeds beyond 40 cm/s, a beep sounds and the scan becomes invalid. Any scan data are not obtained during this time. If the sounds, stop the scan and re-start the scan (from the step (2) above).
(5) As necessary, add antenna markers on the scan screen. Tap [Marker] icon on the main screen or press [Antenna mark] button on the sensor unit (Refer to Figure 1-2 ) to add an antenna mark. When the antenna marker is added, a mark is displayed on the distance scale. The antenna marker is useful to show the location of the rebar shown in the drawing or the position of the planned drill hole on the scan screen. 30
(6) As necessary, perform the image processing of Real time manual subtraction. Waves reflected by objects to be probed (e.g., reinforcing steel) at a position near the concrete surface are difficult to identify because they are combined with waves reflected by the concrete surface (called surface waves). This product contains the standard surface wave data (fixed surface wave data) with which it eliminates the influence of the concrete surface waves in real time by subtracting the fixed surface wave from the received reflection signal. By performing this image processing, you can more easily identify the object location. However there are some cases for example, special conditions (very humid surface, lightweight concrete, etc.) of the concrete surface, where subtracting the fixed surface wave cannot remove the influence of the surface wave due to the difference between the fixed surface wave and the actual surface wave. In such case, horizontal lines (noise) may appear near the surface. In this case, you can use the actually received signal as the surface wave in place of the fixed surface wave. The image processing using the actually received surface wave is called real time surface wave processing. The real time surface wave processing can remove the horizontal lines near by the surface. To use the real time surface wave processing, move the fixed cursor to the position where any embedded objects are not detected, then tap [Image processing] icon (Figure 4-1 ). (Refer to Figure 3-4.) Move the fixed cursor on the position of no embedded object. Tap [Image processing] icon. Surface wave Figure 3-4 B Mode scan result (during scanning) 31
(7) Stop the scan. Tap [ Start] icon (Refer to Figure 4-1 ) of the main screen or press [Start] button on the sensor unit (Refer to Figure 1-2 ) to stop the scan. Then a beep sounds twice and the scan is stopped. Figure 3-5 shows an example of the scan result. ([ Start]
icon is displayed as [] during the scan, and after the scan stopped, its shape changes to [ ].) Note Figure 3-5 Example of B mode scan result
When moving the sensor unit at the speed beyond 40 cm/s, a beep sounds and the scan becomes invalid. No scan data is obtained during this time.
The final scanned point of B mode data represents the data obtained at the position of the line between both side LEDs (Refer to Figure 1-2 ) of the sensor unit showing the center of the sensor units built-in antenna.
The scan is automatically stopped when the sensor unit stays at a position more than 8 seconds.
(8) As necessary, optimize the sensitivity, color, image processing. By changing the sensitivity, color, image processing settings, find for the best settings to get the scan result which provide easy identification of the object position.
(9) Store the data into the file. Tap [File /Print] icon on the main screen to save the scan data into the file or print out the scan data to the external printer. 32 Interpreting the scan results 3.4. Here describes the general procedure to identify position of the detected object. When the scan result shown in Figure 3-6 is obtained after the rebar detection, the image of the detected rebar would have the inverse U shape as shown in Figure 3-6. By using this description, you can determine that a rebar is located at the reverse U shape. The position of the detected object can be determined from the obtained image as described below. Position of the moving direction: Top of the inverse U shape (See in Figure 3-6) Rough Depth (Cover width): Center of the inverse U shape (See in Figure 3-6) To reduce the depth error of the detected object, perform the depth calibration (Refer to Section 4.11.1 Device setting: [Relative permittivity) and identify the depth from A mode wave shown in the BA mode display (Refer to Section 4.6 [Display mode] icon. The depth of the detected object (a rebar, etc.) is matched with the right side peak of A mode wave. You can get the exact depth value by moving the cursor exactly on the peak of the A mode wave. Position of rebar shown in the scan results (The mark is not shown in the actual scan results.) 200mm Measurement direction Start 300mm 60mm 120mm 180mm 240mm Vertical cross sectional drawing of objects to be probed

[Relative permittivity] icon 4.7.
[Relative permittivity] icon allows you to set the relative permittivity (dielectric constant) of the scanned concrete for the scan result at the idle state and to perform the depth calibration. (The setting made by this icon is valid only for the scan result image displayed at the idle state. After starting a new scan, the setting for the measurement is restored to the original device setting. For more details on device setting, refer to Section 4.11.1 Device setting: [Relative permittivity] menu.) The available range of the relative permittivity is from 2.0 to 20.0. (Refer to Section 4.7.1 Relative permittivity.) The current setting is shown on the label of the icon. Figure 4-11 shows the example of the icon label of the relative permittivity setting 8.0. You can set the relative permittivity with the following procedure.
(1) Tap [Relative permittivity] icon. The relative permittivity setup screen appears

Relative permittivity and depth calibration The relative permittivity is an object-specific coefficient showing the relationship between the electromagnetic propagation speed in the air and scanned medium. This product measures the time between the time of transmitting the signal and the time receiving the signal reflected at the embedded object, then calculates the depth of the embedded object by using the measured time and electromagnetic propagation speed determined by the relative permittivity of the scanned medium Depending upon the relative permittivity entered, this product can correct the depth scale on the scan screen. Therefore setting the appropriate value to the relative permittivity is the key factor to get the accurate depth of the detected object. For the theory of operation, refer to 8 Theory. Depth calibration is performed by estimating the relative permittivity of the scanned concrete and setting the value to the relative permitivity. When the relative permittivity of the scanned concrete is known, enter the known value to the relative permittivity. For the setting procedure, refer to Sections 4.7 [Relative permittivity] icon and 4.11.1 Device setting: [Relative permittivity] menu. To reduce depth error when the relative permittivity of the scanned concrete is unknown, perform the depth calibration before the scanning with the following procedure.
(1) Scan the object whose actual depth is known (Ex. the rebar with a known depth or a wall with the known width) and detect the depth of the object.
(2) Adjust the relative permittivity value so that the depth displayed in the scan result matches with the known depth. When the object with a known depth is not avaialble and the relative dielectric constant of the concrete is unclear, it is recommended to set 8.0 (+0) as the relative permittivity. Note
The relative permittivity depends on the condition (such as moisture content) of the concrete being scanned. Therefore the more difference between the actual relative dielectric constant of the concrete and the entered value, the more the depth error. Set an appropriate value to this parameter to get the accurate depth. 50
[View range] icon 4.8.
[View range] icon allows you to change the view range for the scan result displayed at the idle state. (The setting made by this icon is valid only for the scan result image displayed at the idle state. After starting a new scan, the setting for the measurement is restored to the original device setting. For the setting as the devie setting, refer to Section 4.11.3 Device setting: [View range] menu.) The view range specifies the displayed range of depth and distance in B mode screen. Select the adequate range matched with the depth of the scan target as follows. The available settings are Shallow, Normal, Deep, Shallow Wide, Normal Wide, and Deep Wide.

Use the +side (+1 and +2) to increase the sensitivity and the side
(-2 and -1) to reduce the sensitivity. The sensitivity by the depth consists of two levels: S
(shallow) and D (deep). Select shallow when scanning the object at a depth less than 10 cm and deep when scannning the object at a depth of 10 cm or more. The setting AS (A Shallow) is appropriate for scanning the steel bar at the depth less than 10 cm in the normal concrete. The initial sensitivity setting (default) at the factory shipment is AS (A Shallow). Note
The setting made by [Sensitivity] icon is valid only for the scan result displayed at the idlestate. After starting a new scan, the setting for the measurement is restored to the original device setting.. For the setting as the device setting, refer to Section 4.11.2 Device setting: [Sensitivity] menu.

1) Tap [Image processing] icon 2) Image processing setup screen Figure 4-14 Image processing setup screen 54 4.10.1. Image processing The original scan data includes always unnecessary reflected signals (for example, the reflection wave from the concrete surface (surface reflection wave) or reflection wave from the boundary of concrete layers) which is commonly distributed over the scan image. These unnecessary reflection waves make the image decoding difficult. Image processing aims to remove or reduce the unnecessary reflection waves by data processing (subtraction, averaging, and so on) and to provide easy deciphering of objects that are being probed from the scan result. This product supports the image processing listed in Table 4-2. Three image processing can be performed in real time during scanning. The other image processing are applicable to the scan result only at the idle state. Peak processing is applied to the image data obtained by an image processing. Table 4-2 shows which image processing is applicable in real-time during scanning and can be combined with the peak processing. For the image processing applicable at the idle state, refer to Section 4.10 [Image processing] icon. For the image processing applicable in real-time during scanning, refer to Section 4.11.4 Device setting: [Image processing] menu. This section describes the details of each image processing.

Fixed surface processing This image processing subtracts the predefined data of the typical concrete surface reflection wave from the displayed scan data. Usually it can reduce the concrete surface reflection wave to provide easy image decoding. The predefined data used in this image processing is called the fixed surface reflection wave which is generated at the factory by using typical concrete and is stored in the non-volatile memory of the sensor unit. Note
The scan result file stored into the data storage contains the raw scan data, the information about the selected image processing, and the fixed surface wave data used for the image processing. When the data is recalled from the file, NJJ-200 application displays the scan image by using the recalled data (raw scan data, the image processing setting, and the fixed surface wave data). After scanning, NJJ-200 application displays the scan image obtained by performing the selected image processing and the fixed surface wave data prepared in the sensor unit. 4.10.3. User surface processing This image processing subtracts the user defined surface reflection wave from the raw scan data. The user defined surface reflection wave is registered by selecting a point in the actual scan data. Then this image processing subtracts the actual reflection wave selected in the scan data, so that it can reduce the affection (noise) of the concrete surface reflection wave more accurately than the fixed surface wave processing. The user surface reflection wave can be defined and registered by the following procedure.
(1) Scan the concrete. After the scan completed, the scan result image is displayed on the screen.
(2) Move the cursor to the area on the scan result image where you want to do the processing. Make sure not to put the cursor directly on the point with a reflection signal (echo) from any embedded objects.
(3) Tap [Image processing] icon. Then the image processing setup screen appears.
(4) Tap User surface processing and confirm that the mark is attached to the selected setting. Then tap [Processed at the current cursor.] and confirm that a mark is displayed in the [].
(5) Tap [OK]. Then a message Are you sure to update the user surface wave data? [Cancel] [OK] appears. Tap [OK].

The data file in the data storage contains the raw scan data, the image processing setting, and the fixed surface wave data used in the image processing. When the data is recalled from the data file, the scan result image is displayed by using the recalled data (raw scan data, the image processing setting, and the fixed surface wave data). However, the NJJ-200 application will displayany newly scanned images by using the image processing and the fixed surface wave data prepared in the sensor units settings.
You can register a point in the recalled scan result as the user surface wave. After recalling the scan result, perform the procedure above to register a point of the recalled scan result as the user surface wave.
When the point showing some reflection signal from the embedded object is registered as the user surface wave, the image processing may produce unwanted noise on the scan result image.
When the unwanted noise appears after the image processing, register a different point with no reflection signal on the scan result as the user surface wave. 58 4.10.4. Subtraction This image processing is used to reduce the horizontal band noise of the reflection wave appearing at the depth more than 20 cm as shown Figure 4-16 1). You can use this image processing with the procedure below.
(1) Scan the concrete. After the scan completed, the scan image is displayed on the main screen.
(2) Move the cursor to the area on the scan result image where you want to do the processing. Make sure not to put the cursor directly on the point with a reflection signal (echo) from any embedded objects.

When tapping [OK] without the mark at [Processed at the current cursor]
at the step 4) above, a message No processing point defined appears and the processing is canceled.
When re-executing the manual surface wave processing or the subtraction processing (including real-time manual subtraction processing) without the mark
at [Processed at the current cursor], the processing is executed by using the reflection wave data previously registered and shown by the cursor mark on the distance scale. To change the reflection wave data used for the processing, perform the steps 2) to 4) above.
For the real-time subtraction processing, refer to Section 3.4 Interpreting the scan result.
The processing of the manual surface processing is almost same as that of the subtraction processing. The difference is that the manual surface processing subtracts the surface reflection wave data from the scan result only for the depth range of 0 mm to 200 mm. The subtraction processing subtracts the surface reflection data from the scan result over all depth range.
The subtraction processing may remove the reflection wave from the opposite

When the registered surface reflection wave contains some signal reflected from the embedded object, the processing may produce the unwanted noise. 60 4.10.5. Manual surface processing This image processing is used to reduce the remained noise even after an image processing (Refer to Figure 4-17 1)) . This image processing subtracts the registered surface reflection wave from the scan result only for the depth range of 0 mm to 200 mm. You can perform this image processing with the following procedure.
(1) Scan the concrete. After the scan completed, the scan image is displayed on the main screen.
(2) Move the cursor to the area on the scan result image where you want to do the processing. Make sure not to put the cursor directly on the point with a reflection signal (echo) from any embedded objects.

For the manual surface wave processing, refer to Section 4.10.5 Manual surface
When the registered surface reflection wave contains some signal reflected from the embedded object, the processing may produce the unwanted noise. 62 4.10.6. Averaging This image processing is effective to reduce the horizontal line noise appearing uniformly over the scan result. It subtracts the averaged wave of all scan points from the scan result and displays the processed image. This processing may remove the continuous reflection signal appearing at the constant depth like the reflection from the opposite side of the concrete wall. Use this processing by considering this point. You can perform the average processing by the following procedure.
(1) Scan the concrete. After the scan completed, the scan image is displayed on the main screen.

This processing reduces the horizontal line noise appearing uniformly over the scan result, so that it may remove the similar image of the continuous reflection signal appearing uniformly at the constant depth like the reflection from the opposite side of the concrete wall. 63 4.10.7. Peak processing This image processing is effective to remove the unwanted image caused by the ringing in the reflection wave from the detected object (steel bar) and to show the refection wave only from the detected target. Use this processing when the depth of the detected object is difficult to read due to the images of the ringing. This processing is not applicable to the detection of the object (ex. cavity) with the relative permittivity lower than that of the concrete. This processing is applicable to the processed image obtained by fixed surface wave processing (including real-time surface wave processing), average processing, subtract processing, manual surface wave processing, user surface wave processing, or the original image.

Before printing out, the printer setup is required. Make sure to complete the printer setup described in Section 5.8.1 Preparation for the printer.
The printer is dedicated to NJJ-200 Handy Search. It is not applicable to the any other Handy Search model.
Make sure one Smartphone is paired to only one printer for Bluetooth pairing. Smartphone does not allow you to select one from some available printers. The scan data is printed out to the printer detected by Smartphone first of all.
The print out is made in monochrome of 16 gradation). The printed image is not the same as that of the scan image displayed on Smartphone.
The print out of the scan data is compressed to fit for printing. Although the position of the cursor and marker may be slightly moved on the print out, however, the coordinate information of the cursor and marker is not changed.
Make sure to use the recommended print paper. 118 Note
For detailed information about the printer, refer to the printer manual. The range of printing is from the scan start point (0 m) to the scan image displayed on the main screen. To print out all the scan data, scroll the main screen to the end of the scan position and print out the scan data.
The direction of printing depends on the scan direction (forward or backward).
The speed of printing slows down in accordance with the battery voltage of the printer. Change the battery as soon as possible when the speed of printing out is slowing down.
When a message Low printer battery voltage. [OK] during printing or at the start of printing appears, it means that the battery voltage of the printer is dropping. Turn off the printer and change the battery with a fully charged one.
When a message No print paper. Turn off the printer and supply the paper to the printer. [OK] during printing or at the start of printing, the printer is in out of paper. Turn off the printer and supply the print paper. (If the paper was supplied when the printer is turned on, the next print out will not be executed correctly. In this case, cancel the print out, and cycle the power of the printer.)
For the scan data of the distance more than 10 m scanned with the distance correction 13, when printing it in Wide (W) view range (Shallow W, Normal W, Depth W), the printed image may be difficult to recognize. 119

When tapping [OK] without putting into [Applies to the measurement], the new relative permittivity is applied only to the scan image displayed currently, but not to the relative permittivity of the device setup which is used in scanning. The next scanning is made by using the original relative permittivity in the [Device setup: Relative permittivity] menu, but not using the new value defined in the procedure above. 124 6.2. Procedure to mark the rebar This product is equipped with a chalk guide at the front and rear edge of the sensor unit. By using the chalk guide, you can easily mark the rebar position on the concrete during the scan. The marking is made at the position where the fixed cursor position is matched with the rebar position (peak of the inverse U shape shown in the B mode display). This section describes the procedure to mark the rebar on the concrete. 6.2.1. Forward scan marking When scanning forward, the chalk guide at the rear panel is used to mark the rebar position. Move the sensor unit so as for to superpose the rebar position (peak of the inverse U shape shown in the B mode display) on the fixed cursor. Then mark a line on the concrete along the rear chalk guide. Adjust the sensor unit position to superpose the fixed cursor on the rebar position. Make a line along the rear chalk guide. Figure 6-6 Forward scan marking 125 Adjust the sensor unit position to superpose the fixed cursor on the rebar position. 6.2.2. Backward scan marking When scanning backward, the chalk guide at the front panel is used to mark the rebar position. Move the sensor unit so as to superpose the rebar position (peak of the inverse U shape shown in the B mode display) on the fixed cursor. Then mark a line on the concrete along the front chalk guide. Make a line along the rear chalk guide. Figure 6-7 Backward scan marking Note
This product supports the back scroll capability. The marking can be made by confirming the rebar position while moving the sensor unit forward and backward.
This product does not have the imitation of the scan distance. Therefore, you can make the marking without considering the distance limitation. The scan data shown on the main screen and saved into the file is maximum 15 m data of the latest scan data from the scan stop point. 126 6.3. AutoMark function AutoMark is the function which automatically analyzes the scan data, detects the position of the embedded object, and adds a marker on each of all detected objects. This function improves the work efficiency of adding markers on the rebar position for the relatively easily analyzable scan data (in which the detected objects has wide pitch and is located at shallow area) at the field. This function is aimed to add markers on the rebar of the upper level, so that this function may not add markers correctly on the cavity position or the lower level rebar. (This function provides good detection performance for the rebar with the cover width (depth) 100 mm and the rebar pitch 75 mm). You can use this function with the procedure described below. Caution
AutoMark function provides a guide of detecting the rebar in the scan data. It may cause wrong detection or detection failure of the rebar. After executing AutoMark function, confirm the detected and added marker placed on the rebar in the scan image visually. JRC assumes no liability for any damage (such as damage caused to rebars, electrical pipes, gas pipes, etc.) arising from scan results using this product.
AutoMark function deletes all registered markers in the selected marker group and executes the automatic detection. When you need to refer to the registered markers later, save the scan result, then execute Auto Mark function. Note
AutoMark function can add maximum 99 markers for each marker group. When the number of added markers reaches to 99, it does not add any markers for the rest of the scan data.
You can perform marker operations (addition and deletion) for the scan data after AutoMark function is executed. Marker operations may make marker numbers not sequential. In that case, you can re-number marker numbers to be sequential by using Sort marker function. For Sort marker function, refer to Section 6.6 Sort marker.
When the measurement mode is set to time, AutoMark does not add markers

The processing time of AutoMark function depends on the scan data. For the scan data of long distance, it takes around 10 seconds.
The AutoMark result (number of detected rebars) and the position (coordinate) of each added marker may vary according to the search direction of Auto Mark function. 131
(8) When no rebar is detected and no marker is added in AutoMark processing, a message Any markers not detected appears a while and disappears automatically. Figure 6-15 Message when no marker is added. 132 6.4. Location notification function Location notification function is the function available during the scan and assists to show the rebar position by beeping and lighting the front and rear LED every time when the fixed cursor is superposed on each marker position. This function is similar to and can be used in addition to the AutoMark function which automatically analyzes the scan data, detects the position of the embedded object, and adds a marker on each of all detected objects. This function improves the work efficiency of adding markers on the rebar position for the relatively easily analyzable scan data (in which the detected objects has wide pitch and is located at shallow area) at the field. This function is aimed to add markers on the rebar of the upper level, so that this function may not add markers correctly on the lower level rebar or the rebar at the cavity position.
(This function provides good detection performance for the rebar with the cover width
(depth) 100 mm and the rebar pitch 75 mm). You can use this function with the procedure described below. Caution
AutoMark function provides a guide of detecting the rebar in the scan data. It may cause wrong detection or detection failure of the rebar.

Sort marker Sort marker is the function which re-numbers ID numbers of all registered markers from the search start point or from the search end point. Marker operations (deletion or addition) may make marker numbers not sequential which is inconvenient in making a detection report. By using this function you can easily get sequential ID numbers for all registered markers. This section provides an example using Sort marker to re-number non-sequential marker ID numbers which is caused by adding a marker manually at the rebar not detected by AutoMark function. Caution Cautio
After executing Sort marker, you cannot restore the marker ID numbers into the previous state. If you need to refer later to the scan data with the marker ID numbers before sorting, save the scan data into the file and execute Sort marker function.
When two markers are located at the same distance, Sort marker assigns the ID number from the marker at the shallower area.
Marker ID numbers obtained by Sort marker are reflected to the marker list and the detailed marker list.

Theory The principle of this product is basically the same as for general radars widely used at present. Electromagnetic waves are transmitted from the antenna toward the concrete as shown in Figure 8-1. The electromagnetic waves are reflected by an interface with the reflecting objects (e.g., rebars or cavities) whose electrical property is different from that of concrete. The waves are reflected back onto the surface of concrete and received by the receiving antenna placed near the concrete surface. The distance to the reflecting objects can be calculated from the time the reflected waves need to reach the receiving antenna. The horizontal locations of the objects can be detected by moving the main unit on the surface of concrete. Since this product is designed to probe objects with high resolution that are near from the surface of concrete, it transmits electromagnetic waves with the very narrow pulse width of about one nanosecond (one-billionth of a second) or less.
