Level D22 horizontally

Calibrate the horizontal spirit levels

You can calibrate the spirit levels on the D22 laser transmitter. This is done at factory, but should be redone prior to a job. The spirit levels are scaled to 0.02 mm/m [4 arc sec.]. By calibrating the spirit levels and then use them to level the laser transmitter, you can achieve an absolute levelling of the laser plane of approximately 0.01 mm/m [2 arc sec.].

Level

  1. Place the D22 laser transmitter on a flat and stable surface.
  2. Level the laser transmitter according to the spirit levels. Use the tilting screws.

Level the laser transmitter

 

Zero set

  1. Place the detector at a distance of 5-10 metres. Make sure that the laser beam hits the detector target.
  2. Tap to open the program Values.
  3. Tap to zero set.

5-10 m between laser and detector

Index and level

  1. Rotate the D22 180º and turn the laser beam to the detector.
  2. Level the laser transmitter according to the spirit levels. Use the tilting screws.

Rotate laser transmitter 180º and level the laser transmitter.

Adjust value

  1. Tap to halve the value.
  2. Adjust the V-value to 0.00 using the tilting screw.

Halve value and adjust to 0.00 using this tilting screw.

Calibrate first spirit level

  1. Calibrate the spirit level using a hex key.
  2. Repeat step 6–9 to control.

Calibrate the spirit level using this screw.

Calibrate second spirit level

  1. Rotate the D22 90º and turn the laser beam to the detector.
  2. Repeat step 4–12.

Adjust second spirit level.
