9.7.3.2 Calibrate PLD (Power Laser Diode)
Calibration of the PLD is performed on this page. Current power values are shown and new ones are entered here.
For GLM01, adapter
<Endo> is used. Make sure the correct adapter is selected before calibration.
9.7.4 Short calibration guideline
– target laser TLD (aiming beam)
This chapter will guide you through a short calibration routine of the target laser diode.
Use a power meter, measurement unit WATT to perform measurement.
Perform measurement at the fibre connector at the front panel.
Procedure:
1. Start the laser in such a way that the aiming beam can be measured (

9.7.3.1, procedure 1
–6). The aiming beam is on
as soon as “Laser ON” is activated.
2. Measure the aiming beam at level 9 (

9.7.3.1).
3. Change new value until a value of minimal 700µW is shown on the measurement device.
4. Enter a higher or a lower value; corresponding to the measured one. If the value is out of tolerance (700µW ± 300µW),
repeat 1-4.

5. Click on <Write config.>
6. Change the value to 8 and back to 9 again (to ensure the setting change).
