Care And Maintenance; Cleaning And Drying - Hilti PT 10 Manual De Instrucciones

After measuring for approx. 50 seconds, either the green
or the red LED lights to indicate whether the laser tool
under test is within the specified accuracy. If the green
LED lights, the laser tool is within the specified accuracy.
If the red LED lights, the laser tool is not within the
specified accuracy and should be returned to a Hilti
service center for calibration.

7.7 Repeating the test procedure
NOTE
The test procedure can be repeated with each Hilti laser
tool as often as desired.
7.8 Calibration
NOTE
Monitoring of measuring equipment for users certified in
accordance with ISO 9000X: The required procedure for
monitoring the PT 10 quick check device within the scope
of ISO 900X can be carried out by the owner. The PTA 20,
a tool specially designed for the purpose of calibrating the
PT 10 quick check device, is available from Hilti. Please
contact Hilti Customer Service for information about the
availability of this item.

NOTE
Calibration should be carried out at regular intervals. The
PTA 20 calibration tool, to be used for calibrating the
PT 10 quick check device, is available from Hilti . The
calibration tool should be sent to a Hilti service center in
advance for checking and calibration.
1. Mount the calibration tool on the tripod adapter of
the PT 10 (15).
2. Plug the supply cord of the calibration tool into the
power outlet.
3. A message appears in the display and the present
accuracy deviation is shown. The calibration se-
quence number is also shown. The calibration se-
quence number increases by one after each suc-
cessful calibration of a PT 10 quick check device.

8 Care and maintenance

8.1 Cleaning and drying

1. Blow dust off the lenses.
2. Do not touch the glass or the filter 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.

4. Check the bubble level of the optical level again and
correct the level if necessary by turning the optical
level adjusting screws.
5. Switch on the PT 10 quick check device.
6. Use the tip of a pointed object such as a ball-point
pen to press the calibration switch (16) on the panel
at the rear of the device.
The small red LED on the right lights indicating
calibration mode (18).
7. Select filter setting II. The accuracy class does not
have to be selected.
8. Turn the crank to adjust the height of the PTA 20
calibration tool (16) so that the laser beam emitted
is aimed at the center of the crosshairs on the PT 10
quick check device.
The position of the laser beam on the camera lens
is indicated by the LEDs.
9. Turn the fine adjustment screw (17) on the PTA 20
until the display shows "zero".
NOTE The direction in which the fine adjustment
screw should be turned is indicated by the two ar-
rows in the display. The arrows at the beginning of
the line indicate the direction in which the fine adjust-
ment screw should be turned and the subsequent
digits indicate the present deviation / inclination in
arc seconds and arc minutes.
10. Both yellow LEDs light up as soon as the laser beam
strikes the camera. At the same time, the "Start
measuring" button becomes active and the device
is ready to begin the test.
11. If neither of the yellow LEDs (19, 20) light up or only
one LED lights, turn the fine adjustment screw on
the optical level until the laser beam is found.
12. Press the "Start measuring" button (21). The meas-
uring operation is indicated by the yellow LEDs blink-
ing and continues for a maximum of 50 seconds.
NOTE Do not touch or move the PTA 20 calibration
tool or the PT 10 quick check device while measuring
is in progress. An error message will be displayed in
the event of vibration.
The green LED lights after successful calibration and
the PT 10 returns to normal operating mode. The
small red LED on the right goes out.
8.2 Storage
Remove the appliance 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.
After a long period of storage, check the calibration of
the tool before use.
8.3 Transport
Use the Hilti shipping carton, the Hilti shipping case
or packaging of equivalent quality for transporting or
shipping your equipment.
