8.1
Calibration check
WARNING
You must wear the supplied laser protective goggles during the entire calibration
procedure.
The following section describes the procedure for calibrating the SIROLaser.
We recommend performing this check at least once a week.
In order to enable exact inspection of the performance and flawless
functioning of your SIROLaser unit, we recommend performing calibration at
three different power levels:
1 W
3 W
5 W
The SIROLaser performs a self-calibration. During this procedure, the system
checks that the laser emission parameters are correct. We recommend that
you check these values using a suitable external measuring instrument at
least every six months. If the measurement readings indicate a wavelength of
970 nm +/- 15 nm, a power of 0.5 to 7 W and a resolution of 5% or higher, the
calibration is correct.
8.1.1
Calibration check without an external power meter
WARNING
You must wear the supplied laser protective goggles during the entire calibration
procedure.
Connect an optical fiber to the SIROLaser.
Point the optical fiber in the air point in a controlled direction.
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".
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.
Test for 3 W
Release laser radiation again until the message "OK" appears.
Test for 5 W
Release laser radiation again until the message "OK" appears.
Quit the calibration menu by pressing the "LEFT ARROW" key.
