Check & Adjust
4.1
Overview
Description
Leica Geosystems instruments are manufactured, assembled and adjusted to the
best possible quality. Quick temperature changes, shock or stress can cause devia-
tions 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.
Electronic adjust-
ment
The following instrument errors can be checked and adjusted electronically:
If the compensator and the horizontal corrections are activated in the instrument
configuration, every angle measured in the daily work is corrected automatically .
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
ATR
ATR zero point error for Hz and V - option
