8 Checking the Unit's Accuracy
The accuracy of the laser beam should be checked regularly. This requires a free measuring
length of 10 m. The check is carried out in two steps.
Step 1
• Position the X-Liner 5.2 as shown in the figure to the
right.
• Switch on the horizontal beam at the X-Liner 5.2.
• Mark point A on the laser line.
• Rotate the X-Liner 5.2 through 180° and mark point B
on the laser line.
Step 2
• Position the X-Liner 5.2 opposite as shown in the
figure to the right.
• Align the X-Liner 5.2 with marking B.
• Rotate the X-Liner 5.2 through 180°.
• Measure the plumb distance H between marking A and
laser line C*.
• If the measured distance H between marking A and
laser line C* < 6 mm, the X-Liner 5.2 is within the
tolerance range.
* The laser line C can be both above or under marking
A.
Note: If the plumb distance H measured between marking A and laser line C is outside the
tolerance range, the X-Liner 5.2 must be checked by an authorised customer service or by
NEDO.
