Check & Adjust

Overview

Leica Geosystems 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:
• Crosshairs offset
• V-index
• Tilt sensor

All calibration settings can also be reset to factory default.
During the manufacturing process, the instrument errors are carefully determined and
set to zero. As mentioned previously, these errors can change and it is highly recom-
mended to redetermine them in the following situations:
• After rough or long transportation
• After long storage periods
• If the temperature difference between the current environment and at the last cali-
bration is more than 20°C

Tilt Sensor Calibration

Before Calibration:
a
3D Disto_033
a) Tilt sensor offset
Step Description

This calibration is done automatically. You must only ensure that the 3D Disto
is set up < 3°.
1. Calibration is started in Menu » Device » Calibration.
2.
Press .
3D Disto starts self-levelling automatically: the tilt is checked and the instru-
3.
ment levels itself if the tilt is < 3°.

Pop-up prompts Don't touch 3D Disto about 1 minute!
4. If ok, pop-up prompts Calibration successful.
