18.3 Adjustment of Compensation Systematic Error of Instrument

1 Vertical axis error
2 Collimation axis error
3 Vertical angle 0 datum error
Correction constants for the above errors are calculated and stored in the instrument by the following
procedure, and then measurement values are corrected using the stored constants. This adjustment
has a direct effect on determining the coordinate origin. Carry out the adjustment very carefully.
Operating procedure
