survey meter line of Mirion Technologies by offering modern design and versatile functionalities for radiation measuring applications. RDS-32 is a small handheld, battery-operated radiation survey instrument. Models RDS-32 and RDS-32iTx utilize an energy-compensated GM-tube as primary detector. RDS-32WR and RDS-32iTxWR offer an extended measurement range by addition of a silicon diode detector. RDS-32iTx and RDS-32iTxWR models are equipped with an internal radio module enabling the dose/dose rate data transmission to any WRM compatible system. Additionally, but not featured in this manual, the product family includes RDS-32iTxSD variant for specialized long-

term monitoring applications. RDS-32 is suited for a wide range of applications in civil defense, industrial use, nuclear power plants, laboratories etc. CSW-32 Configuration Software can be used to easily optimize the behavior of the instrument to meet various working conditions and needs. With the CSW-32 user can define menu functions available on the meter itself from the bare essentials to a full functioning menu including alarm limit setting. RDS-32 features excellent ergonomics; it is lightweight and easy to handle with visual and audible alarms and a built-in vibrating alarm. The instrument can be handled firmly even under difficult conditions thanks to the rubber grip around the instrument. The large graphic display can be easily read both in total darkness and in direct sunlight. The display additionally includes a tilt sensor enabling display rotation in menu mode. RDS-32 can be operated with a single key (on/off) or taking advantage of the 4-way menu navigation. To facilitate easy operation of the instrument, shortcut functions have been configured to the arrow keys and marked with corresponding symbol. The predefined shortcuts include backlight activation, accumulated dose display and a mute function. With configuration software users can also customize the shortcut keys. RDS-32 features both Bluetooth and NFC connectivity. A dedicated smart phone application is provided for changing meter settings and accessing measurement data. RDS-32 offers versatile possibilities to measure other types of radiation by using external probes. These detectors include an extensive range of CSP (Canberra Smart Probe) probes for gamma, alpha, beta and neutron measurements in various applications. The compatible probes also include GMP-12 series external gamma probes and GMP-25, ABP-150 and GMP-

11-3/15-3 probes for alpha/beta contamination measurements. The various detectors can be added to the instrument using a connecting cable or an adapter cable. This provides users an easy and cost-effective way to extend their measuring capabilities. The meter provides an additional protective function to the user: while using external probes, the meter simultaneously measures and displays the dose rate from the internal detector of the instrument. This allows the alarm to be triggered in case a too high dose rate or an accumulated dose is measured. 1 INTRODUCTION 1.2 RDS-32 VARIANTS The RDS-32 variants are available either in Sv-units or in rem-units. 1 2 3 4 For more information see the back label of the meter and the detailed specifications in Chapter 6 SPECIFICATIONS. 2 RDS-32 with BLACK front frame includes two variants for different dose rate areas 1 2 RDS-32 for max dose rate 100mSv/h RDS-32WR for max dose rate 10Sv/h WR is marked on the upper right corner of front frame iTx variants have a distinctive frame color.

1.14 HISTOGRAM Disabled, 10, 15, 20, 60, 100, 600, 1000 or 6000 cps. The default setting in the RDS-32 is that the histogram is ON and collecting data at a 5 minute interval. The meter memory is able to store approximately 60000 data sets. The information stored is the immediate value in the display, the average and maximum dose rate from the previous storing, the location and time. When an external detector is connected to the instrument, the histogram stores data from both internal and external detector. The final number of stored data sets depends on the amount of diagnostics information that is also stored into the same memory area. The histogram memory is downloaded using the configuration software and communication link. It will take approximately 80 hours to fill the RDS-32 histogram memory when sampling at 10 second intervals. If the histogram memory becomes full the older data sets will be overwritten by new data sets. In addition to the type of data sets mentioned above there are automatic records that are stored into histogram memory:

Diagnostics (Automatic, manual or error found) The user has reset the dose or the max dose rate The instrument has been calibrated (New and old Coefficients are stored) These data records also consume the histogram memory. Calibration memory: The results of the 64 newest calibrations are stored in the memory. The oldest are overwritten in case more than 64 calibrations are performed. Diagnostics memory: The first start-up of the day is stored here. In case the instrument operates continuously without going to the OFF state, automatic diagnostics is run at 00:00:00 and the results are stored into a specific diagnostics memory. This memory can store the data 16 of over one year of operation. When the memory becomes full, the oldest diagnostics data is overwritten. These special memory areas cannot be cleared with the configuration software but require special service. RDS-32 MENU IT The histogram memory can be cleared by selecting Clear in the HISTO menu. 1.14.1 CLEAR 1.14.2 STATE The current state of the histogram data collection can be checked and changed ON/OFF in the STATE menu. NOTE: With configuration software user can configure the instrument to automatically save histogram data when alarm conditions are met, although the histogram STATE would be set to OFF. See the software manual for more details 17 RDS-32 MENU IT 1.14.3 INTERVAL (I) 1.14.4 LOCATION (L) The interval of storing measurement results to the histogram can be selected from the predefined list in this menu by pressing the Menu/Select key. The intervals available are 10 s, 30 s, 1 min, 5 min, 10 min, 30 min, 1 h and 2 h. A location can be stored as additional information to the histogram. There are up to 255 numbered locations. The location 0 is a general-purpose placement. Using the RDS-32 configuration software it is possible to specify a mnemonic or longitude and latitude values for the first 16 locations. By selecting Manual, the user can save the current values displayed by the meter into the histogram. 1.14.5 MANUAL 1.15 CONNECTIONS 18 RDS-32 MENU IT 1.15.1 WRM WRM (Wireless Remote Monitoring) functionality can be enabled with configuration software. The WRM communication uses either internal WRM-radio in applicable models or serial line wired connection. The WRM can be set OFF or to send messages in intervals between 2 seconds to 2 hours. The WRM functionality is used to send data packets via radio system, RS communication or over Local Area Network. In RDS-32iTx variants an internal radio modem enables the dose/dose rate data transmission to any WRM compatible system. In RDS-32iTx variants the WRM setting are available in the menu as default. To activate the WRM communication in an RDS-32iTx variant:

Scroll to WRM in the menu and check the current state of the communication link

(WRM: xs | WRM:OFF ). Change WRM ON/OFF and send interval as needed. 1.15.2 BLE 1.15.3 NFC BLE communication can be configured in the BLE menu. The user can manually activate BLE enumeration for 30 s or use NFC pairing. The user can also disable to BLE communication in this menu. NFC Pair => activated with NFC (Standby STBY) ON for 30s => Manual activate BLE enumeration active for 30 seconds OFF => Disable the BLE communication Basic device configurations can be performed via BLE interface by using dedicated Mirion application. The NFC Tag mode can be set ON when BLE communication is initiated with NFC reader or OFF when BLE communication needs to be initiated via BLE menu selection, see 1.15.2. Tag mode ON/OFF 19 RDS-32 MENU IT 1.16 DIAGNOSTICS The user can manually activate the meter self test in the DIAG menu. The DIAG menu also contains information about the device firmware version and the time and date set to the RDS-32. The time and date can be set using the configuration software. The firmware can also be updated using configuration software. See the software manual for more details. Activate the meter self test routine by navigating into the DIAG menu and by pressing Menu/Select on Self test. The self test routine includes checking the high voltage, the operating voltage and the battery capacity. During this process the user may also check the operation of all the display pixels, the visual alarm LED, the audible alarm and the vibration alarm. Selecting CAL Check starts the calibration check procedure. The check dose rate value is set to 1 mSv/h as a default. With the configuration software, the value can be set to a more optimal value between 300 Sv/h - 3 mSv/h. After a fixed 1 minute waiting time the instrument measures a dose of 100 Sv (time calculated from the rate). In case the measured dose is within 10% from expected dose the check is cleared, otherwise there will be a warning and it is advised to perform a recalibration of the instrument. Start the calibration check procedure. The results of the check are stored into the Diagnostics histogram. 1.17 PROBES Most probes are detected automatically, and the radiation detection starts immediately without any need for input. Probe menu opens when detector with no memory is connected to the meter. From this sub-

menu it is possible to change the detector profile, unit for external detector. For isotope profile detectors there is the possibility to change the used isotope. It is also possible to change radiation type for detectors that are capable to detect different radiations. Gen.CHK.Def is profile for no-memory detector that is tested for the pulse generation of the external probe. If no pulses are detected for a given time the meter will show error message. 20 Gen.No.Def is profile for no-memory detector that is not tested for pulse generation. For instance alpha probes, and there are no pulses at all (some of the probes are alpha sensitive only) in the determined time window. ERROR CODES AN ERROR CODES AND OTHER DISPLAY MESSAGES When necessary the meter will give display messages regarding battery condition, current alarms, and error situations. 1.18 LOW BATTERY WARNING An audible low battery warning signal combined with a blinking battery symbol indication repeated every 6 minutes when the battery capacity is 10% < Capacity < 30%

Low battery warning: _______ _ _______ (Long Short Long Bleep in five minutes intervals). The dose rate measurement continues normally. 1.19 LOW BATTERY ALARM The display shows "LOBAT" blinking and the audible alarm is activated when the battery capacity is <10%. Low battery alarm: _______ _ _______ (Long Short Long Bleep in 20 second intervals). NOTE: The dose rate measurement is prevented. 1.20 DOSE RATE / DOSE ALARM (BLINKING DISPLAY) Dose rate alarm: ------ (two beeps per second). The dose rate display is blinking, and the continuous audible alarm is on. The audible alarm can be silenced with mute shortcut (right arrow key). Dose alarm: - - - - - - (one beep per two seconds). The dose rate display is on and the current dose alarm level alternates in the display and the continuous audible alarm is on. The audible alarm can be silenced with mute shortcut (right arrow key). 21 ERROR CODES AN 1.21 DOSE RATE OVERFLOW ALARM (OFL) When the measurement limits are exceeded, the display shows OFL (blinking). The continuous audible alarm is on. Dose rate overflow: ____ ____ (continuous beeps). The overflow alarm cannot be reset. NOTE: When the dose rate overflow has been activated, there will be a message from this event in the dose read-out. When the dose is given, the display alternates between DR.OFL <-> dose. This flag will be set when the dose is reset. This is to inform the user that the measured dose might not give the true value due to exceeding the maximum measurable dose. 1.22 DEFECT ERRORS In case there is a critical internal failure in the instrument, the Defect error is activated. The continuous audible alarm is on. Error alarm: _______ _______ (continuous bleeps every two seconds). The dose rate measurement is prevented. Error codes and types:

Error1 = CAL.DF Calibration error, the calibration coefficient is default, or is out of accepted limits. Error2 = FLS.DF Non-volatile memory error Error3 = DET.DF Detector is faulty (internal or external) Error4 = DG1.DF High voltage is not within specified range Error5 = DG2.DF Internal power supply is out of specified range Error6 = DG3.DF Firmware CRC error; the bit sum check of embedded software failed Error7 = LFE.DF Cumulative dose overflow (>10 Sv). The GM-detector can be at the end of life. Should an error occur, write down the Error message and return the meter to the manufacturer for service (for contact info: see the last page of this manual). The internal diagnostics memory will also store critical errors, but in case the problem is the memory itself, it cannot be completed. 22 MAINTENANCE AN MAINTENANCE AND DECONTAMINATION No specific maintenance is required except for a periodic check of the calibration. The local authorities typically determine the required checking interval. Once a year under demanding conditions, or every second year under typical laboratory conditions is a recommended interval in maintaining the proper operational reliability of the instrument. 1.23 FIRMWARE UPDATE Configuration software is needed for firmware update. Follow the procedures outlined in the software manual to upload a new firmware to the RDS-32. 1.24 BATTERY COVER AND SEAL CHANGE For battery cover and seal change a replacement cover or seal and a Pozidriv #1 screwdriver are needed.
