Accuracy test (fig. III-VI)
Perform the accuracy test before using the device
for the first time, then at regular intervals. In case
of deviations, send the device to Würth Master
Service.
Horizontal accuracy (fig. III)
Set up the device between two walls, maintain
■
a distance of approx. 0.3m from one and 10m
from the other wall.
Switch on the 360° horizontal line and all
■
vertical lines.
Mark point a
on the wall in approx. 0.3 m
■
1
distance (intersection of horizontal and vertical
line).
Mark point b
on the wall in 10 m distance.
■
1
Turn the device by 90°.
■
Align the horizontal beam such that it is identical
■
in height with point a
Now measure the difference between the hori-
■
zontal beam and point b
Note
The specified accuracy is the maximum
difference allowed.
Turn the device twice in steps of 90°.
■
Vertical accuracy (fig. IV)
Set up the device at a distance of 5 m from a
■
wall.
Hang a plumb bob with a rope of at least 2 m
■
length on the wall.
Switch a vertical line on.
■
Align the vertical line with the plumb line.
■
Measure the difference D4. The distance should
■
not exceed half the value of the specified
accuracy.
Repeat this procedure with the second vertical
■
line.
