9.7.2 Fibre check
If the deviation is higher than expected, check power directly at the laser module:
STEP 1:
1.
2.
3.
4.
5.
6.
7. Disconnect fibre cable from laser
module.
Protect end of fibre cable with the
cap attached to the fibre itself.
Connect test fibre of measuring sen-
sor head to laser module.
Set external fibre detection to
“NO”
(see

9.7.1.2).
Measure power and compare it with
the intended value.
If the value is within the tolerance,
exchange the fibre (see

11.3.4).
Calibrate as described in

9.7.
If the power at the module itself matches the values submitted at the software, then the power loss is caused by the fibre
(narrow radii or kinked).
