14 Check & Adjust
14.1 Overview
Description Leica 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 can be done in the field by running through specific measurement procedures.
The procedures are guided and have to 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:
Every angle measured in the daily work is corrected automatically if the compensator
and the Hz-correction are activated.
Mechanical adjust-
ment The following instrument parts can be adjusted mechanically:
•
Circular level on instrument and tribrach
• Laser plummet
l, t Compensator longitudinal and transversal index errors
i Vertical index error, related to the standing axis
c Hz collimation error, also called line of sight error
