Your question:
The laser line becomes weaker or blurred?
Possible cause:Soiled optical window
Measure:The optical windows have a special antireflection coating. Therefore clean the optical windows with a cotton bud and white spirit. Please do not use any aggressive detergents.
Your question:
No laser beam?
Possible cause:- Instable power supply or defective fuse.
- No voltage supply.
- Incorrect beam positioning.
- The plug is not inserted in the power pack or screw connections are loose.
- The excess temperature fuse on the power pack is activated due to temperature overload.

Recommendation:
We recommend the use of a MSK (magnetic voltage stabiliser). Check whether the laser is supplied with electricity. Please pay attention to the following for the ZA range: remove the switch, clean and attach correctly. Check the laser beam positioning. Insert the connection plug in the power pack, switch off the power supply and leave the device to cool down.
Your question:
Noise development during operation/laser light flickering?
Possible cause:Instable power supply or defective power pack.
Measure:Check the power supply. Please send us the unit if there is no improvement.
RecommendationWe recommend the use of a MSK (magnetic voltage stabiliser).
Your question:
Crooked projection line?
Possible cause:For HeNe laser: out of focus optic
For diode lasers: defective diode
Measure:Please contact our service team.
Your question:
ZPT-F range: split laser line?
Possible cause:Defective diode due to instable power supply
Measure:Check the power supply. Please send us the unit if there is no improvement.
Recommendation:We recommend the use of a MSK (magnetic voltage stabiliser).
Your question:
ZPT-F range: the laser switches off and back on again after a short time?
Possible cause:The laser's ambient temperature is too high. The integrated cooling system automatically switches off from 40°C.
Measure:Shield off from other possible sources of heat. Do not expose the laser to direct sunlight.
Your question:
