Product Manual

Tribrach: If the bubble extends beyond the circle, adjust it using the adjustment pin in conjunc-
tion with the adjustment screws. Turn the adjustment screws:
•
To the left: and the bubble approaches the screw.
•
To the right: and the bubble goes away from the screw.
4 Repeat step 3 on the instrument and tribrach until both levels are centered and no further
adjustments are necessary.
After the calibration, no adjustment screw should be loose.
6.1.5 Inspecting the Laser Plummet of the Instrument
The laser plummet is integrated into the vertical axis of the instrument. Under normal conditions
of use, the laser plummet does not need adjusting. If an adjustment is necessary due to external
influences, the instrument has to be returned to a GeoMax service department.

zontal surface, such as a sheet of paper.
