Checking the unit's accuracy
The accuracy of the laser beam should be checked regularly. This requires a free measuring
length of 30 m. Four measurements are taken in total (two measurements each in X/Y axis).
The check is carried out in two steps.
Step 1 – x-axis
• Position the GEMINI R as shown on the right,
along the x-axis marked on the housing and
switch on the rotating laser. The laser beam
starts to rotate.
• The position of the laser beam is now determined
with the help of the receiver.
• Mark position A of the laser beam.
Step 2 – x-axis
• Rotate the GEMINI R through 180°.
• Repeat the preceding steps again and mark the
position B of the laser beam.
• Measure the plumb vertical distance H between
marking A and marking B, this can be above or
below mark A.
• If the measured distance H between marking A
and marking B < 6 mm, the GEMINI R is within
the tolerance range.
Steps 1 and 2 now have to be repeated as
described for the Y-axis.
Note: If the plumb measured distance H between marking A and marking B is outside the
tolerance range, the GEMINI R must be checked by an authorised customer service.
Function - how the receiver works
The receiver's sensor window detects the position
of the laser dot (laser line) and therefore enables
work
• on weak reflecting or dark surfaces
• outdoors
• in poor visibility, e.g. in the event of strong
sunshine.
