Dont collimate the sun directly Avoid insolating the instrument, and dont collimate the sun directly for protecting eyes and instrument. Set up the instrument on the tripod When using it please insure the connection between tripod and instrument is firm. It is better to work with wooden tripod for the measurement accuracy. Assemble the tribrach on the instrument The setting of tribrach would influence the accuracy.The tribrach should be check frequently, the screw which connects the tribrach and alidade must be locked tightly. And the central fixing screw should be tight. Avoiding the librations on the instrument When transporting, keep the instrument in the case and try your best to lighten librations. Carry the instrument When carryingthe instrument handle must be held tight. High temperature condition If put the instrument in high temperature condition for a long time, it is bad for the instrument performance. Temperature changing sharply The sharp temperature changing on the instrument or prism will shorten the distance measurement range, for example, after taking the instrument out from a warm car to a cold condition, wait for some time, it can be used when it adapts to the surrounding condition. Check the battery power Before using it, you should check the power whether it is enough. Take out the battery It is not suggested to take out the battery when the instrument is on, otherwise, the stored data may be lost, so it is better to replace the battery after power off the instrument. Stored data responsibility STONEX should not be held liability for the lost data because of wrong operation. The noise from the instrument When the instrument is working, it is normal if you hear the noise from instrument motor, it will not affect the instrument work. 3 Definition of Indication For the safety of your product and prevention of injury to operators and other persons as well as prevention of property damage, items which should be observed are indicated by an exclamation point within a triangle used with WARNING and CAUTION statements in this manual.

Preparation before Measurement 2.1About Battery 2.1.1 Battery Power Symbol Measurement is possible The battery is lower, it is better to replace or recharge it Measurement is impossible, it is necessary to replace or recharge battery Note:

1)The batterys working time will be affected by many factors, such as ambient temperature, recharging time, recharging and discharging times. So we suggest the users recharge the battery full or prepare several full batteries before operation. 2)The battery symbol only indicates power capability for current measurement mode. The power consumption in distance measurement mode is more than in angle mode, if the instrument enters into distance measurement mode from angle mode, the power maybe auto-off because of lower battery. 3)The symbol only indicates the supply power but not the instantaneous power change. 12 And if the measurement mode changes, the symbol will not show the powers decrease or increase immediately. 4)It is suggested that user should check every battery power before field work. 2.1.2 Replace and mount battery 1Replace battery Press the button downward as shown left. Remove the battery by pulling it toward you. 2) Mount battery Insert the battery to the instrument. Press the top of the battery until you hear a click. 2.1.3 Recharge battery 1)Connect the charger connector to the battery. 2)Plug the charger on 100V/240 power supply.The red lamp becomes lighting,which indicates recharging.If interval-time is longer,the connector isnt fixed well. 3) That the green lamp flashes means recharging is complete. Note:

1 New battery (or battery does not used for several months) should be recharged for several times.Please recharge it more than 10 hours, and then the battery can attain best status. 2 Please recharge the battery continuously for another 1~2 hours after the light green,which is good for the battery. 13 2.2 Setting up the instrument 1) Set up the tripod first: Extend the extension legs to suitable lengths and tighten the screws on the legs.Make sure the legs are spaced at equal intervals and the head is approximately level. Set the tripod so that the head is positioned over the surveying point. Make sure the tripod shoes are firmly fixed in the ground. 2)Attaching the instrument on the tripod head: Mount the instrument carefully on the tripod head. Supporting it with one hand, tighten the centering screw on the bottom of the unit to make sure it is secured to the tripod. 2.3 Centering 2.3.1 Centering with Optical Plummet (Optional) Crossmark Plummet Center Optical plummet Turn the focusing ring of the optical plummet to focus the ground mark point. Then adjust three foot-screws to center the bubble of the circular level. If the plate level is not leveling-up, you can loosen the center screw of the tripod, and move the instrument to 14 center the bubble of the plate level. At last tighten the center screw.Repeat above steps until the center of reticule always coincides with the mark point when rotating alidade of instrument. Note: Use the three leveling screws and tripod to center the instrument. 2.3.2 Centering with Laser Plummet External influences and the surface conditions may lead to the requirement of the adjustment of the laser intensity.The laser can be adjusted in 25% steps as required.If the instrument is equipped with laser plummet,after activating electronic level,the laser plummet adjusting bar will display.With pressing up or down keys the laser lightness can be adjusted. Operation Steps:

1) Press the Func key,and then click F1 to enter into the display as shown in the upper figure.With pressing up or down direction keys you can turn on or off laser plummet and set it as four levels of brightness.Thus,that laser emits downwards can be seen. 2) Loosen the center screw of tripod,and move the base plate on tripod head until the laser spot coincides with ground mark point.Then tighten the center screw. 3) Repeat leveling and two steps until the instrument keeps leveling and the laser spot coincides with ground mark point when rotating alidade of instrument in any direction. 4) After centering,please turn off laser plummet to save power. 2.4 Levelling-Up 2.4.1 Basic Levelling-Up with the circular level Screw A Screw B 1. Move the foot screws A and B in opposite direction till the circular bubble is perpendicular to a line shaped with screw A and B. The direction of rotation in left thumb indicates the movement of the circular bubble. Screw C 15 Screw A Screw B 2. Move the bubble to the center of the circle by turning screw C. Screw C 2.4.2 Accurate Levelling-Up with plate level Screw A Screw B 1. Loosen the horizontal motion clamp, and turn the Plate level Screw C Screw A Screw B instrument till the plate level is parallel to a line shaped with screws A and B. Adjust the screws A and B to make the bubble in the center of the level. 2. Loosen the horizontal motion clamp, and turn the instrument approximately 90.Adjust the screw C until the bubble in the center of the level. Screw C 3. Repeat above steps until the bubble remains in the center of the plate level while the instrument is rotated to any position. 2.4.3 Accurate Levelling-Up with Electronic Level on the screen It is convenient for R25 to level up with electronic level, especially when it is difficult to observe the circular level and plate level. 1)Firstly,power on the instrument,press Func button,and then select F1(Level/Plummet).The electronic level displays on screen. 2)Secondly,level it by turning three foot screws and ensure the bubble is in the plate level.Make sure the black spot is in the center. Note:On this menu you can turn on/off the X/Y compensator by pressing left or right 16 direction key. 2.5 Input mode Due to the alphanumerical keypad you can enter characters directly. 1) Numeric fields:Can only contain numerical values.By pressing a button of the numeric keypad the number will be displayed. 2) Alphanumeric fields:Can contain numbers and letters.By pressing a button of the alphanumeric keypad the input opens. By pressing several times you can toggle through the characters. For example: 7->A->B->C->7->A.... 2.5.1 Insert characters If a character was skipped(e.g.13 instead of 123),you can insert it later. Place cursor on 1 Insert an empty character on the right of 1(Press F1 key) Input the new character 2 Confirm input. 2.5.2 Delete characters Place cursor on character to be deleted Delete this character(Press F2 key) Confirm delete. 2.5.3 Clear characters Place cursor on any position among character fields Clear characters(Press F3 key) Confirm Clear. 2.5.4 Toggle through characters By pressing a button of the alphanumeric keypad the input opens. By pressing F4 key you can switch between numbers and letters.Here at entry status pressing F4 is equivalent to pressing shift key. 2.6 Pointsearch Pointsearch is a global function used by applications to e.g. find internally saved measured or fixed points.It is possible for the user to limit the point search to a particular job or to search the whole storage.The search procedure always finds fixed points before measured points that fulfill the same search criteria. If several points meet the search criteria, then the points are listed according to their age. The instrument finds the most current (youngest ) fixed point first. Direct search By entering an actual point number (e.g. "A10") all points with the corresponding point number are found. 17

[VIEW]:Displays the coordinates of the selected point.

[ENH]:For manual input of coordinates.

[JOB]:To select a different job.

[ENT]:Confirm selected point. 2.7 Wildcard search The Wildcard search is indicated by a "*". The asterisk is a place holder for any following sequence of characters.Wildcards are always used if the point number is not fully known, or if a batch of points is to be searched for. Examples:

* : All points of any length are found. PT :All points with exactly the point number "PT" are found. PT* :All points of any length starting with "PT" are found (e.g.:PT1, PT12, PTAB).

*1 :All points of any length with a "1" as the second character are found (e.g.: A1, B12, A1C). A*1 :All points of any length with an "A" as the first character and a "1" as the third character are found. (e.g.:AB1, AA123, AT17). 2.8 Measuring After switching on and setting up correctly, the Total Station is immediately ready for measuring.On the measurement display it is possible to call up functions of fixed keys and function keys. 3 Function key Under FUNC menu several functions can be activated.Functions can also be started directly from the different applications.Each function from the FUNC 18 menu can be assigned to the USER key.The detailed applications are described below. 1) Level/Plummet This function triggers the electronic bubble and enables the settings of intensity for the laser plummet. 2) Target Offset If it is not possible to set up the reflector directly, or it is not possible to aim at the target point directly, the offset values(length, cross and/or height offset) can be entered. The values for the angle and distances are calculated directly for the target point. L_Off-

Press the [CODE] softkey.The code that was input can be searched for within the codelist and it gives the possibility to add attributes to the code. Quick coding:

Press the [Q-Code] softkey and enter the shortcut to the code. The code is selected and the measurement starts. 2) Stake Out This program calculates the required elements to stake out points from coordinates or manually entered angles, horizontal distances and heights.Stake out differences can be displayed continuously. Stake out coordinates from memory. Procedure:

Select the point.

[DIST] Start measuring and calculation of the stake-out elements.

[REC] Save the displayed values.

+N Station E:Easting offset between stake out and actual point. N:Northing offset between stake out and actual point. 3) Free Station The application is used to determine the instrument position from measurements to a minimum of two known points and a maximum of five known points. H N Station E The following measurements sequences to target points are possible:

a)Horizontal and Vertical angles only (resection) b)Distances and Horizontal and Vertical angles (3 points resection) c)Horizontal and Vertical angles to some point(s) and Horizontal and Vertical angles plus distances to other point(s). The final computed results are Easting,Northing and Height of the present instrument station,including the instruments Horizontal Circle Orientation.Standard deviations and residuals for accuracy assessments are provided. Measuring facilities Single face I or II or dual face I + II measurements are always possible.No specific point sequence or specific face sequences are required.Gross errors checks are made for dual face measurements to ensure the same point(s) are sighted with the other face. Note:If a target point is measured several times in the same telescope position the last valid measurement is used for computation. Measurement Disciplines:

27 2 face measurements When measuring the same target in both faces,the reflector height mustnt be changed when changing the telescope position. Target points with 0.000 height Target points with 0.000 height are discarded for height processing.If target points have a valid height of 0.000 m,use 0.001 m to enable it for height processing. Computation procedure The measuring procedure automatically determines the method of evaluation,e.g. resection,3 point resection,etc.If more than the minimum required measurements are performed,the processing routine uses a least squares adjustment to determine the plane position and averages orientation and heights. a)The original averaged measurements of face I and face II are called into the computation process. b)All measurements are treated with the same accuracy,whether these are measured in single or dual face. c)Easting and northing is determined by the method of least squares,including standard deviation and improvements for horizontal direction and horizontal distances. d)The final height (H) is computed from averaged height differences based on the original measurements. e)The horizontal circle orientation is computed with the original averaged measurements of face I and face II and the final computed plane position. Procedure:

a)Set job b)Set accuracy limit:

28 Here you can define a limit for the standard deviation values.If the calculated deviation exceeds the limit,a warning dialog box ejects,which reminds you whether to proceed or not. c)Input of the name of the station and the height of the instrument. d)Input of the target PtID and the reflector height. e)Measure

Radius:Except the end point of route,the Radius of any point represents the radius of curvature(R in the below figure) of one side preceding main point(Big stake mark direction).When route turns left,the radius will be negative;Conversely,the radius will be positive.When radius of curvature is infinite,the radius value should be set to:99999999.999 or -99999999.999. North:Ordinate of main point East:Abscissa of main point

[2] Intersection Point This application is to describe the entire road with informaiton of intersection point of the route.This method is appropriate for the linetype whose intersection points are symmetrical,and start point and end point of the route must be on the straight line segment or its vertex points.That intersection points are symmetrical means their corresponding tangent lines are equilong.In the dialog of View Road(2D)-Intersection,existed main points only can be available for scan and deletion but not edit.

Offset:Distance between the point to be stake out and its corresponding mileage of centreline(Not always the perpendicular distance from stake out point to centreline).That this value is 0 indicates middle-stake.But if this value is negative,it means left side-stake;Otherwise,it means right side-stake. Def.Ang(Deviation Angle):Included angle generated from centreline and connecting line between the point to be stake out and its corresponding mileage of centreline.And its range is 0,.Its necessary to refer to deviation angle when set out particular point(such as bridge pier) and side-stake whose connecting line is not orthogonal but intersected with the route. Specific meaning with respect to Stake Distance,Offset and Deviation Angle is 51 shown in the below figure:

Note:1.Make sure Offset,Deviation Angle and Stake Distance are set correctly when peg stake out. 2.With the increment of main point datum of plane alignment,running speed of certain links during peg stake out can be slowed down. 3.Peg stake out result can be used as transect measure result. b)Transect Measure On Road Stake Out display,press softkey F2 or numberkey 2 to access Transect Measure dialog.

The assembling, transportation and operation will cause this error. Note: After the program correction this deviation error is also on the instrument. 1) Check Set-up the instrument on tripod or adjustment platform and leveling accurately. Aim at the cross-hairs of collimator or the obvious target at a distance. Get the face left angle reading F1 and the face right angle reading F2. Calculating the horizontal collimation error C according to C=Fl- F2180/2,if C<8, no adjustment will be necessary. If C>8, proceed with the following adjustment. 2) Adjustment by program Set up the instrument on tripod or adjustment platform, and leveling accurately. Procedure:

Power on, run the Hz-Collimation to access collimation error process. Aim at the cross-hair of collimator at telescope left,and itll display the horizontal and vertical angles. 74 Aim at the cross-hair of coillmator at telescope right,and itll display the horizontal and vertical angles. The software will calculate the new collimation error and vertical index error automatically. Press F3 to view Calibrate Data. Note:

The adjustment can be performed by the program when C<30, if C>30, adjust the reticle. Reticle Adjusting:

Rotate the instrument in face right position, turning horizontal tangent screw until F2=F2+C. Loosen the shield of telescopes reticle. 75 Adjusting two screws at left and at right until the vertical hairs of telescopes reticle coincides with the cross-hairs of collimator or target. Repeat the check and adjustment procedure until the error is accepted. Note:

When adjust the screws of reticle, firstly loosen the screw on the moving direction of reticle, secondly tighten another screw by the same mount, clockwise turning is for tightening, and anticlockwise turning is for loosening, the turning mount for tightening or loosening should be same. After the reticle adjustment, it is necessary to adjust the vertical index error by program. 9.1.2 Vertical Index Error The deviation between vertical circle zero position and horizontal direction is vertical index (i), it is necessary to concern this error when measure vertical angle. The instrument program applied a formula to remove this error. This correction can offer the index for the formula. Warning: Before starting this operation, be sure to read manual carefully, otherwise it may cause data faulty. Because of the close relationship between vertical index and compensator zero position, it is necessary to check and adjust compensator zero position when adjust the vertical circle, the value should be stable when reading. 1) Check Please adjust the reticle of telescope and correct the collimation error before this operation. Mount the instrument at the tripod or a stable device and level it accurately, then turn on the instrument. Aim at the cross-hairs of collimator or the obvious target at a distance, VA should be about 10.Read the face left angle Fl and face right angle F2. Calculate the index error according to the formula below:

i = ( Fl+F2-360)/2 If I<10, no adjustment is necessary , or you have to adjust it. 2) Adjustment by program Set-up the instrument on tripod or adjustment platform, and leveling accurately. Procedure:

Power on, run the V-Index to access vertical index error process. Aim at the cross-hair of collimator at telescope left, and itll display the horizntal and vertical angles.

Kpt274.417-0.2905*p/(10.0036*t).. RTS Kpt278.960-0.2902*p/(10.0036*t)...RTS Where: p--Pressure value (hPa) t--Temperature value () Kpt--Atmospheric correction (ppm) Example:

t=20, p=1013hpa, L0=1000m. Then: Kpt=0ppm (RTS) Kpt=4ppm (RTS) L=L0(1+Kpt)=1000(1+010-6)=1000.000m (RTS) L=L0(1+Kpt)=1000(1+410-6)=1000.004m (RTS) The atmospheric value is obtained easily with the atmospheric correction chart. Find the measured temperature in horizontal axis, and pressure in vertical axis on the chart. Read the value from the diagonal line, which is the required atmospheric correction value. 89 For RTS series 90 Appendix II: Correction for refraction and earth curvature Considering the correction of refraction and earth curvature for distance measurement, the formula for slope distance, horizontal distance and vertical distance applied in the instrument are as followings:

The conversion formula for horizontal and vertical distance is as follows when correction for refraction and earth curvature is not applied:

HD=SD COS VD=SD SIN Note:

The factory setting for the refraction coefficient K is 0.142.
