8 Checking the Unit's Accuracy
EN
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 3
as shown in the figure to the
right.
• Switch on the horizontal beam at the
X-Liner 3
.
• Mark point
A
on the laser line.
• Rotate the
X-Liner 3
through 180° and mark point
B
on the laser line.
Step 2
• Position the
X-Liner 3
opposite as shown in the figure
to the right.
• Align the
X-Liner 3
with marking
B
.
• Rotate the
X-Liner 3
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 3
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 3
must be checked by an authorised customer service or by
NEDO.
9 Troubleshooting
Note:
If the errors cannot be rectified using one of the listed remedies, the
