8.4 Calibration and adjustment

8.4.1 Calibration
Monitoring of measuring equipment for users certified in
accordance with ISO 900X: As specified in ISO 900X, you
may carry out the inspection and testing of the PD 5 laser
range meter yourself (see ISO 17123-4: Field procedures
for testing geodetic and surveying instruments: Part 4, Elec-
tro-optical distance meters).
1. Select a readily accessible measuring distance of a known
length (approx. 1 to 5 meters / 3 to 15 feet) which does
not change over time and measure the same distance 10
times.
2. Determine the mean deviation from the known distance.
This value should be within the specified accuracy toler-
ance for the tool.
3. Keep a record of this value and note the date when the
next test is due.
Repeat this test at regular intervals as well as before and
after important measuring tasks.
Apply a test and inspection confirmation sticker to the
PD 5 and keep a record of the entire monitoring, test and
inspection procedure and the results.
Please refer to the technical data contained in the operat-
ing instructions and the information concerning measur-
ing accuracy.
8.4.2 Adjustment
To ensure that the laser range meter is adjusted correctly,
we recommend that it is returned to a Hilti Service Center
for calibration. Accurate adjustment of the tool will be con-
firmed by a calibration certificate.

8.4.3 Hilti calibration service

We recommend that the tool is checked by the Hilti calibra-
tion service at regular intervals in order to verify its reliabil-
ity 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 specifi-
cations given in the operating instructions. The tool will be
readjusted if deviations from the manufacturer's specifica-
tion are found. After checking and adjustment, a calibration
sticker applied to the tool and a calibration certificate pro-
vide 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.
