5.1 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
adjustment The following instrument errors can be checked and adjusted electronically:
