Care And Maintenance; Cleaning And Drying - Hilti PD-E Mode D'emploi

The Offset function automatically adds or subtracts a
predefined value to or from all measurements. This value
can be entered manually or measured.
1. Select Offset from the group of special functions.
2. In order to enter the distance manually, use the
left or right arrow buttons to select the keyboard
en
symbol.
3. Confirm by pressing the "Measure" button.
4. Use the right or left arrow buttons to select the
corresponding digits.
5. Confirm the digits by pressing the "Measure" button.
6. To confirm the value, select the "tick" symbol in the
lower right corner.
7. Then use the left or right arrow buttons to select the
Offset symbol. The offset you have chosen will then
be shown in the upper area of the display. The cho-
sen offset will then be added to or subtracted from
every measurement you take (depending whether
the value entered is preceded by a plus or minus
sign).
NOTE As an alternative to entering the offset dis-
tance manually, the offset may also be measured
with the tool. To do this, select the symbol for single
measurement and confirm your choice by pressing
the "Measure " button. You can then measure the
desired offset distance.

8 Care and maintenance

8.1 Cleaning and drying

1. Blow dust off the lenses.
2. Do not touch the lens with the fingers.
3. Use only a clean, soft cloth for cleaning. If necessary,
moisten the cloth slightly with pure alcohol or a little
water.
NOTE Do not use any other liquids as these may
damage the plastic components.
4. The temperature limits for storage of your equipment
must be observed, especially in winter / summer.
8.2 Storage
Remove the tool from its case if it has become wet.
The tool, its carrying case and accessories should be
cleaned and dried (at maximum 40°C / 104°F). Repack
the equipment only once it is completely dry.
Check the accuracy of the equipment before it is used
after a long period of storage or transportation.
Remove the batteries from the tool before storing it for a
long period. Leaking batteries may damage the tool.
8.3 Transport
Use the Hilti packaging or packaging of equivalent quality
for transporting or shipping your equipment.
8.4 Calibration and adjustment of the laser

7.7.8 Data memory
The tool saves measurements and the results of calcula-
tions continuously while in operation. Depending on the
scope of the function used, a total of up to 30 values,
including graphic symbols, are saved in this way.
When data memory is already filled with the 30 previous
sets of displayed data, the "oldest" set of data is deleted
when a new set of displayed data is saved.
Data memory can be completely cleared by pressing the
"C" button for approx. 2 seconds while data memory is
displayed.
may carry out the inspection and testing of the PD-E laser
range meter yourself (see ISO 17123-4: Field procedures
for testing geodetic and surveying instruments: Part 4,
electro-optical distance meters).

8.4.2 Adjustment of the laser
To ensure correct adjustment of the laser range meter we
recommend that it is returned to a Hilti Service Center
for calibration. Accurate adjustment of the tool will be
confirmed by a calibration certificate.
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.
Determine the mean deviation from the known dis-
tance. This value should be within the specified
accuracy tolerance for the tool.
Keep a record of this value and note the date when
the next test is due.
NOTE Repeat this test at regular intervals as well as
before and after important measuring tasks.
NOTE Apply a test and inspection confirmation
sticker to the PD-E and keep a record of the en-
tire monitoring, test and inspection procedure and
the results.
NOTE Please refer to the technical data contained
in the operating instructions and the information
concerning measuring accuracy.
