Checking the horizontal accuracy
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

of the laser
beam and measure the verti-
cal distance

. This can be
above or below marking

NOTE
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.
