Re-sight the same target within ± 3° of horizontal.
NOTE This step is assisted by the display which shows the differences for the vertical circle and the horizontal
circle. This serves exclusively as a sighting aid.
NOTE The values should be very close to zero, i.e. with a deviation of only a few seconds, when the target is
sighted with the telescope in the second position.
9.
Take the measurement in telescope position 2.
When measurements have been taken successfully in both telescope positions the new and the old settings for
the vertical index and the target axis are shown.
10. Adopt and save the new calibration values.
NOTE New settings for the dual-axis compensator are also determined by way of the calibration procedure for
the vertical index and target axis previously described.
When the new calibration values are adopted, the new settings for the compensator are also adopted.
15.3 Hilti Calibration Service
We recommend that the tool is checked by the Hilti Calibration Service at regular intervals in order to verify its reliability
in accordance with standards and legal requirements.
Use can be made of the Hilti Calibration Service at any time, but checking at least once a year is recommended.
The Calibration Service provides confirmation that the tool is in conformance, on the day it is tested, with the
specifications given in the operating instructions.
The tool will be readjusted if deviations from the manufacturer's specification are found.
After checking and adjustment, a calibration sticker applied to the tool and a calibration certificate provide written
verification that the tool operates in accordance with the manufacturer's specification.
Calibration certificates are always required by companies certified according to ISO 900x. Your local Hilti Center or
representative will be pleased to provide further information.
