14.3 Checking the horizontal accuracy

NOTE
The accuracy of the laser should be checked regularly. This requires a free
measuring length of 30 m. Four measurements are taken in total in AUTOMA-
TIC mode (two measurements each in X/Y axis). The check is carried out in
two steps. The position of the laser beam is determined with the help of the
receiver.
Step 1 – X-axis
• Set up the laser along the X-axis
with a 30 m distance from the
wall.
• Mark the position of the laser
beam (A) on the wall.
Step 2 – X-axis
• Rotate the axis through 180°.
Attention:
The tripod may not be changed
– ideally you should use Nedo
Quickfix®!
• Mark position B of the laser
beam and measure the verti-
cal distance H between marking
A and marking B. This can be
above or below marking A.
• The laser is within the tolerance if
H  3 mm!
Steps 1 and 2 now have to be repeated as described for the Y-axis.
If the value of H is outside the tolerance, the Primus 2 must be adjusted by an autho-
rised customer service agent or by Nedo.
