Safety Notes

Read and observe all instructions. The integrated protections in the measuring tool may be compromised if the measuring tool is not used in accordance with the instructions provided. SAVE THESE INSTRUCTIONS FOR FUTURE REFERENCE.

Have the measuring tool repaired only through qualified specialists using original spare parts. This ensures that the safety of the measuring tool is maintained.
Do not operate the measuring tool in explosive environments, such as in the presence of flammable liquids, gases or dusts. Sparks can be created in the measuring tool which may ignite the dust or fumes.

Keep the measuring tool away from cardiac pacemakers. The magnets 10 generate a field that can impair the function of cardiac pacemakers.

Keep the measuring tool away from magnetic data medium and magneticallysensitive equipment. The effect of the magnets 10 can lead to irreversible data loss.

Product Description and Specifications
Please unfold the fold-out page with the representation of the measuring tool and leave it unfolded while reading the operating nstructions.
Intended Use
The measuring tool is intended for swift finding of pulsating laser beams.

Noise Information
The A-weighted sound pressure level of the audio signal at one meter distance is 80 dB(A).
Do not hold the measuring tool close to your ear!

Assembly

Inserting/Replacing the Battery
Alkali-manganese batteries are recommended for the measuring tool.
Pull the latch 16 of battery lid outward and open the battery lid 15.
Make sure that you insert the batteries at the correct polarity according to the illustration on the battery lid. When the batteries become weak, the LED indicator 3 will begin to flash. It is still possible to work for about 2 hours with the measuring tool.

Remove the batteries from the measuring tool when not using it for extended periods. When storing for extended periods, the batteries can corrode and selfdischarge.

Operation

Initial Operation

Protect the measuring tool against moisture and direct sun light.
Do not subject the measuring tool to extreme temperatures or variations in temperature. As an example, do not leave it in vehicles for a long time. In case of large variations in temperature, allow the measuring tool to adjust to the ambient temperature before putting it into operation. In case of extreme temperatures or variations in temperature, the accuracy of the measuring tool can be impaired.

Setting Up the Measuring Tool (see figure A)
Set up the measuring tool at least 5 m away from the line laser. Switch on the pulse function of the line laser. Select an operating mode on the line laser where either only one horizontal or vertical laser plane is generated.
Note: Do not select an operating mode with both horizontal and vertical laser plane (cross-line operation), as otherwise faulty height indications of the laser beam may occur.
Position the measuring tool in such a manner that the laser beam can reach the reception area 9. Align the measuring tool in such a manner that the laser beam runs laterally through the reception area (as shown in the figure).

Switching On and Off

A loud audio signal sounds when switching on the measuring tool. Therefore, keep the measuring tool away from your ear or other persons when switching on. The loud audio signal can cause hearing defects.

To switch on the measuring tool, press the On/Off button 2. An audio signal will sound and all LEDs will light up briefly.
To switch off the measuring tool, press the On/Off button 2 again. An audio signal sounds three times and all LEDs light up briefly before the tool switches off. The power indicator 3 extinguishes. When no pushbutton on the measuring tool is pressed for approx. 20 minutes and when no laser beam is impinged upon the reception area 9 for 20 minutes, the measuring tool switches off automatically to save the batteries.
Selecting the Setting of the Centre Indicator
With button 1, you can specify the accuracy with which the position of the laser beam is indicated as centred on the reception area:
– “Coarse” adjustment (the direction LEDs 8 and 6 flash).
– “Fine adjustment” (the centre-indication LED 7 flashes),
After switching on the measuring tool, the “fine” accuracy is always set.

Direction Indicators
The position of the laser beam in the reception area 9 is indicated:
– by the direction LEDs “move downward” 8, “move upward” 6 or the centre indicators 7 on the front and back of the measuring tool,
– optionally by the audio signal (see “Audio Signal for Indication of the Laser Beam”, page 17).

Measuring tool too low: If the laser beam runs through the upper half of the reception area 9, then the direction LEDs 6 light up. If the audio signal is switched on, a signal sounds at a high frequency. Move the measuring tool upward in the arrow direction.
Measuring tool too high : If the laser beam runs through the lower half of the reception area 9, then the direction LEDs 8 light up. If the audio signal is switched on, a signal sounds at a low frequency. Move the measuring tool downward in the arrow direction.
Measuring tool centred: If the laser beam runs through the reception area 9 at the height of the centre mark 12, then the centre-indication LEDs 7 light up. If the audio signal is switched on, a continuous tone sounds.

Audio Signal for Indication of the Laser Beam
The position of the laser beam on the reception area 9 can be indicated via an audio signal.
After the measuring tool has been switched on, the audio signal is always set to the low volume level.
The volume level can be increased or switched off.
To change or switch off the audio signal, press the audio signal button 4. When the volume is low, a brief audio signal will sound and the centre- indication LED 7 will light up. When the volume is high, a brief audio signal will sound and the direction LEDs 6, 7 and 8 will light up. When the audio signal is switched off, the LED indicators are extinguished.
Independent of the audio signal setting, a short beep sounds at low volume level each time a button is pressed on the measuring tool.

Working Advice
Marking
When the laser beam runs through the center of the reception area 9 , its height can be marked at the centre mark 12 right and left on the measuring tool.
When marking, take care to align the measuring tool exactly vertical (for horizontal laser beam), or horizontal (for vertical laser beam), as otherwise the marks are offset with respect to the laser beam.
Attaching with the Magnet (see figure B)
When a positive-lock attachment is not absolutely required, the measuring tool can be attached to steel parts via the the magnets 10.
