Operator calibrations

The operator can perform the following instrument calibrations:

• Autolock collimation

• Compensator calibration

• Camera collimation for overview, primary and tele camera

• Plummet camera calibration

• Laser (pointer) collimation (optional)

These calibrations are performed by the field software on the controller. Please refer to the field software documentation for more information.

Trimble recommends that these calibrations are carried out on a regular basis to obtain the highest precision of the instrument.

In addition, Trimble recommends that these calibrations are performed:

• Immediately before high-precision angle measurements in one face

• Whenever the instrument may have been roughly handled during transport

• After extended working or storage periods

• If there has been a significant temperature difference from the previous calibration
