Calibration

Overview

GeoMax instruments are manufactured, assembled and adjusted to the best possible quality. Quick
temperature changes, shock or stress can cause deviations and decrease the instrument accuracy. It is
therefore recommended to check and adjust the instrument from time to time. This check and adjust can
be done in the field by running through specific measurement procedures. The procedures are guided and
must be followed carefully and precisely as described in the following chapters. Some other instrument
errors and mechanical parts can be adjusted mechanically.
The following instrument errors can be checked and adjusted electronically:
l, t Compensator longitudinal and transversal index errors
i Vertical index error, related to the standing axis
c Horizontal collimation error, also called line of sight error
a Tilting axis error
AiM AiM zero point error for Hz and V - option
If the compensator and the horizontal corrections are activated in the instrument configuration, every
angle measured in the daily work is corrected automatically.
The results are displayed as errors but used with the opposite sign as corrections when applied to meas-
urements.
To view the adjustment errors currently used, select MAIN MENU: Apps\Calib\ViewAdjustment Data.
The following instrument parts can be adjusted mechanically:
• Circular level on instrument and tribrach
• Optical plummet - option on tribrach
• Allen screws on tripod
