Accuracy Check

The accuracy of the laser beam should be checked regularly. This requires a free measuring length
of 10 m. The check takes place in two steps.
Step 1
• Position the Quasar 6 as shown in the
figure on the right and switch it on. The hori-
zontal beam is switched on automatically.
• Mark point A on the laser line.
Rotate the Quasar 6 through 180° and
•
mark point B on the laser line.
Step 2
• Position the Quasar 6 opposite as shown
in the diagram to the right.
• Align the Quasar 6 with marking B.
• Rotate the Quasar 6 through 180°.
• Measure the vertical distance H between
marking A and laser line C*.
• If the measured distance H between
marking A and laser line C* is < 6 mm, the
Quasar 6 is within the tolerance range.
* The laser line C may be above or below
marking A.
Note: If the vertical measured distance H between marking A and the laser line C is outside the
tolerance range, the Quasar 6 must be examined by an authorised customer service agent or
by NEDO.
Step 3
Set up the Quasar 6 approx. 5m in
front of a long wall and precisely align the
laser cross with the middle of the wall. Then
turn the laser through 45° to the left and
mark the level of the horizontal line at the
right-hand end of the line in the area of the
middle of the wall (A). Then turn the laser
through 90° to the right (45° to the right
from the middle) and mark the left-hand end
of the horizontal line in the area of the
middle (B). The level difference between
(A) and (B) must not be more than 3 mm.
