9.7.3 Short calibration guideline
– power laser PLD (working beam)
This chapter guides you through a short calibration routine of the power laser diode. All further maintenance must be per-
formed by one of the Oertli Instrumente AG certified service centres.
The power measured at the connector for the laser probe (3) must be within ± 20% of the value set on the screen. If the de-
viation is more than this, the laser must be recalibrated.
Use a power meter, measurement unit JOULE to perform measurement.
Select pulse duration of 1000 ms.
Perform measurement at the connector for the laser probe (3) at the front panel.
Procedure:
1. Connect login as administrator.
2. Click on
<Read config.> (

9.7.1.2)
3. Change equipment type to 3500. (

9.7.1.2)
4. Click on <Write config.>
5. Reboot GML01
6. Check for error messages.(

9.7.1.3)
7. <enable> GLM01 module. (

9.7.3.1)
8. Click on <System ON>.
9. Click on <Laser ON>.
10. Module is heating up (time varies between 10 and 60 seconds).
11.
Go to “calibrate PL” and click on “Endo”
12. Measure the power at 50 mJ / 100 mJ / 200 mJ / 400 mJ / 800 mJ / 1500 mJ at duration 1000 ms
13. Enter measured values minus 3 mW into white boxes (

9.7.3.2) (for example: measure value 37 mW , so enter 34 mW ).
14. 2500mJ must be measured at 500ms, and the result multiplied by 2 (

9.7.3.2)
15. Click on <Accept>.
16. Click on <Write Config>. (

9.7.3.2)
17. Click on <Reboot> (

9.7.1.2) .
18.
Fill in the “Functional Test” form.
19. Set the equipment type back to 3100.
If no separate laser pedal is available, measure all the values ranging between 50 and 2500 mJ in laser mode with the OS 4
in advance.
