8.4 Hilti Measuring Systems Service
Hilti Measuring Systems Service checks the tool and, if
deviations from the specified accuracy are found, recal-
ibrates the tool and checks it again to ensure conformity
with specifications. The service certificate provides writ-
ten confirmation of conformity with specifications at the
time of the test.
The following is recommended:
1. The tool should be checked at suitable intervals,
depending on the frequency of normal use.
2. The tool should be checked at least once a year by
a Hilti Measuring Systems Service Center.
3. The tool should be checked by a Hilti Measuring
Systems Service Center if it has been abused in any
way.
