The tilt sensor option can also be changed in the Parameter Setting Modes. When you change the tilt sensor option in the angle measurement mode, it will change in the Parameter Setting Modes and visa verse.

2.7Compensation of Systematic Error of Instrument

1)Error of vertical axis (X,Y tilt sensor offset)

2)Collimation error

3)Error of vertical angle 0 datum

4)Error of horizontal axis

The above mentioned errors can be compensated by software, which calculated internally according to each compensation value.

Also these errors can be compensated by software collimating one side of the telescope that is carried out to delete the error by turning in normal and reverse both sides of telescope so far.

lTo adjust or reset the above compensation value, see Chapter 9 “CHECK AND ADJUSTMENT” . l Enable you to stop this function, see Chapter 8 “PARAMETERS SETTING MODE” or Chapter 9
