Hilti PR 300-HV2S, Руководство по эксплуатации

Страница: 26 / 31

2. Activate manual electronic inclination alignment on the PR 300-HV2S by pressing the “Electronic inclination
alignment” key.
If the arrows for electronic inclination alignment blink, the PRA 300 is receiving no laser beam from the
PR 300-HV2S.
3. If the left arrow lights, turn the PR 300-HV2S clockwise.
4. If the right arrow lights, turn the PR 300-HV2S counter-clockwise.
When both arrows light, the PRA 300 is correctly aligned.
After successful alignment (both arrows light constantly for 10 seconds), the function ends automatically.
5. Then secure the rotating laser on the tripod so that it cannot be inadvertently moved out of position.
6. You can also end electronic inclination alignment by pressing the “End manual electronic inclination alignment”
key.
NOTE There may be divergence between the results obtained by approximate alignment with the aid of the
visual sighting method (using the front and rear sights) and fine alignment with the aid of manual electronic
inclination alignment. As the manual electronic method is more accurate than the visual method, we recommend
that electronic inclination alignment is always used as the reference.
6.8.3 Measuring a given inclination automatically
16
With this function you can create an inclined laser plane between 2 points automatically and determine the angle of
inclination between these points.
1. Set up the rotating laser at the top edge of the inclined plane as described in 6.8.1.
2. Mount the laser receiver with the PRA 83 receiver holder, for example, on the PUA 53 telescopic staff.
3. Position the receiver immediately in front of the rotating laser, bring it into alignment with the laser plane at the
correct height, and then secure it at the second reference point on the telescopic staff.
4. Position the receiver on the telescopic staff at the lower edge of the inclined plane, click the “Automatic alignment”
key and confirm this by pressing .
NOTE Double-click the AUTO key again to complete the alignment procedure.
The laser plane alignment procedure then begins. A constant signal tone is emitted while this is taking place.
5. The direction of the search can be changed by pressing the “Automatic alignment” key once.
As soon as the laser beam strikes the detection area of the laser receiver, the beam is fixed at the position of the
marking notch (reference plane). Once the position is reached (i.e. the marking notch is found), a signal tone with
a duration of five seconds indicates that the process is complete.
The “Automatic alignment” symbol is no longer shown in the display on the laser receiver and the receiver
switches automatically to normal operating mode.
The new inclination is shown in the display on the laser receiver.
6. Read the inclination between the two points (positions of the rotating laser and the laser receiver) from the display
of the laser receiver.
6.8.4 Setting the inclination with the aid of the PRA 79 slope adapter
NOTE
Check that the slope adapter is fitted correctly between the tripod and the tool (please refer to the operating instructions
for the PRA 79).
1. Set up the PRA 79 slope adapter in a suitable position for the application, e.g. on a tripod.
2. Position the tripod either at the upper edge or lower edge of the inclined plane.
3. Mount the rotating laser on the slope adapter and, with the aid of the sights on the head of the PR 300-HV2S,
adjust the tool and slope adapter so that they are parallel to the inclined plane. The control panel of the
PR 300-HV2S should face away from the direction of inclination.
4. Make sure that the slope adapter is in the zero position (0°).
5. Switch the tool on (see 6.3).
6. Press the “Inclined plane mode” key .
The “Inclined plane mode” LED then lights on the control panel of the rotating laser.
The tool then begins automatic self-leveling. The laser switches on and begins to rotate as soon as this is
complete.
7. On the receiver, now press
to deactivate the leveling function.
8. Set the slope adapter to the desired angle of inclination.
NOTE When the angle of inclination is set manually, the PR 300-HV2S levels the laser plane once and then
subsequently fixes it. Vibration, changes in temperature or other influences that may occur during the course of
the day may affect the position of the laser plane.
NOTE In order to enter digital manual settings for X/Y, you must first set the tool to the standard operating mode.
To do this, the system must be restarted.
