If you performed the test correctly and got an "OK" message for all three
tests, the laser unit has been successfully calibrated.
8.1.2

Calibration check using an external power meter

Required power meter: Tested, traceable power meter capable of measuring
a power level of at least 10 watts.
WARNING
You must wear the supplied laser protective goggles during the entire calibration
procedure.
Connect an optical fiber to the SIROLaser.
Aim the optical fiber at the measuring sensor of the power meter.
Maintain a distance of at least 20 mm between the optical fiber and the
surface of the measuring sensor. This way you can prevent possible
damage to the power meter which might otherwise result from the small
diameter of the optical fiber and the correspondingly high energy density.
Wear the laser protective goggles and verify that the entrance to the room
where the calibration is being performed is controlled by an interlock
device or is locked.
Switch on the SIROLaser and select the "SETUP AREA".
Select "SERVICE".
Make sure that the optical fiber is cut carefully and that the laser beam
projects a red circle. The circle must be as well defined as possible.
The first test (1 W) is highlighted.
Use the "RIGHT ARROW" key to select the test you want to perform
(1 W, 3 W, 5 W). Press the "LEFT ARROW" key to end the test.
Test for 1 W
Release laser radiation with the foot control or finger switch until the
message "OK" appears. Check whether the measured result is within the
permissible range of 1 W +/-20%.
Test for 3 W
Release laser radiation again until the message "OK" appears. Check
whether the measured result is within the permissible range of 3 W +/-
20%.
Test for 5 W
Release laser radiation again until the message "OK" appears. Check
whether the measured result is within the permissible range of 5 W +/-
20%.
Quit the calibration menu by pressing the "LEFT ARROW" key.
If the test procedure runs without errors, the message OK will appear for each
test, and the values measured on the power meter will be within the permis-
sible range. In this case, the unit has been successfully calibrated.
