9.1 Calibration
The inspection, measuring and test
equipment for the range meter must be
certified in accordance with ISO 900X...
You may carry out the inspection,
measuring and test of the PD 30 laser
range meter as specified in ISO 900X...
(See ISO 17123-4 Field Process for
Accuracy Examinations of Geodetic
Instruments:
Part 6, Close-range Opto-electrical Range
Meters.)
Select a readily accessible measuring dis-
tance of a known length approx.
1 to 5 (3 – 15 ft) meters long which does
not vary with time and take five
measurements of the same distance.
Determine the mean of the deviations to
the known distance. This value should be
within the specific accuracy tolerance for
the range meter.
Keep a record of this value and note the
time for the next test.
Repeat this check measurement at regular
intervals as well as before and after
important measuring tasks.
Apply a sticker to the PD 30 documenting
this control of the measuring, inspection
and test equipment for the range meter and
keep a record of the entire control process,
inspection procedure and the results.
Please refer to the technical data contained
in the operating instructions and the
information concerning measuring
accuracy.
9.2 Adjustment
For optimized adjustment, have the laser
range meter adjusted at a Hilti workshop
where accurate adjustment of the range
meter will be confirmed with a calibration
certificate.
9.3 Hilti calibration service
We recommend that you undertake a
regular check of the laser range meter
through the Hilti calibration service in order
to verify its reliability in accordance with
standards and legal requirements.
The Hilti calibration service is available at
all times, but a check at least once a year
is recommended.
As a part of the Hilti calibration service, it
is verified that on the day of the check the
specifications of the range meter comply
with the technical information given in the
operating instructions.
If there are deviations from the manufac-
turer's information, the range meter will
be re-adjusted. After the check and
adjustment, a calibration sticker will be
applied to the range meter, and it will be
verified in writing in a calibration certificate
that the range meter functions in
compliance with the manufacturer's
information.
Calibration certificates are always required
for companies that have been certified
according to ISO 900X...
Your local Hilti contact / representative will
be pleased to provide further information.
