2. Total Station
In-Built Programs
The instrument can perform some of the simple
surveying experiments, independently , such as..
 Remote Elevation Measurement
 Missing Line Measurement
 Area Calculation
 Data Collection

4. Remote Elevation Measurement
 To obtain elevation
K
to the point at which
setting the target
Prism is not
possible, the REM
Program is useful.
Place the prism at any point on the ground in the same vertical plane of the target

8. MISSING LINE MEASUREMENT (MLM)
To obtain the measurement
for horizontal distance
(dHD), slope distance
(dSD), elevation (dVD) and
horizontal angle (HR)
between two target
prisms, the MLM
programme is useful.
The MLM mode has two modes
MLM-1 (A-B, A-C): Measurement is A-B, A-C, A-D, ………..
MLM-2 (A-B, B-C): Measurement is A-B, B-C, C-D, ………..

13. Area Calculation
 To calculate area of a
closed figure AREA
Programme is useful.
 There are two
methods to calculate
the area of the figure.
 Area calculation from
coordinate data file.
 Area calculation from
measured data

14. The procedure for the area calculation from measured data is as
follows.

17. Character of the Surveying
1.Field Work.
2.Office Work.
The field work consists of the measurement of angles,
distances and elevations and the keeping of a record of what
has been done in the form of field notes (DATA COLLECTION)

18. Data Collection ..
Need..
For true representation of field conditions.
To plot the plans and sections with desired accuracy

23. Data Collection..Cont..
Carrying out BM
 Press Menu key
 Goto page 2
 input the instrument height and reflector height
 Input the station coordinates as ( ex: 1000, 1000, 300 m).

24. Data Collection..Cont..
 Sight the prism held on B.M.
 The difference in Z will be displayed
Depending on the line of sight, add/subtract accordingly
the difference in Z to the R.L. of the B.M. to get the R.L.
of the station point

25. Data Collection..Cont..
RECORD
 Press MENU key.
 Create a file in coordinate (NEZ) mode.
 Input occupied point data and Back sight data/
Direction.
 Go to Side shots and orient the telescope towards the
prism held at various intermediate station points as per
the visibility.

26. Data Collection..Cont..
 Before going to shift the instrument, note down the last
point data as change point. A peg mark of identification
of the change point should be fixed.
 Shift the instrument to the change point and set it there.
 Input last point data as occupied point data. Again, after
input the instrument height and reflector height, orient
the telescope to the back sight station and continue the
process to other points.

27. INSTRUCTIONS FOR OPERATION AND MAINTENANCE :
The following are the instructions to be followed for better results.
Instructions for Instrument Maintenance :
Always bring foot screws to the center of its run before
levelling it up.
Always see that both the locks are released before turning the
instrument.
Make sure that the clamps of the tripod are fixed firmly.
Hold the handle of the instrument before fixing and at the time
when it is to be removed for further shiftngs.

28. •Batteries should be discharged for every ten charging
completely, so that the life of the batteries will be increased.
•Always cleans the lens with cloth after the days work is finished.
•Make sure that the legs of tripod (bottom shoe) should be
cleaned daily.
•Close the foot screws completely after the instrument is to be
changed its position.
•Fix the instrument as per its position specified in the box and
close the box.

29. Instructions for Operations Maintenance :
When ever we are working in Distance mode ( ) or Co-ordinate mode ( )
to come out press (Ang) button key (Esc-Escape key will not work).
•Make sure that the measured filed is downloaded first to out PC and they
only it is to be deleted.
•Always select the occ-point / BS point from the list only and then press
enter.
•When ever Reflector Height is changed during side shot measurement
make sure that the changed height is edited properly before measuring.
•Orientation is must after every shifting.
•To make internal display unit on, press * (star) button and then press F1.
•If it is required to change prism constant from ‘0’ to ‘-30’, press * (star)
button and then press PSM/PPM and then change the prism constant by
pressing ‘EDIT’ .
