Calibration instructions
The following equipment is required for calibration:
•
Power meter (Ophir or equivalent)
•
Potentiometer adjustment tool
•
Digital voltmeter (Fluke 77 or equivalent)
WARNING -
As a precaution against accidental exposure to the output beam
or its reflection, personnel checking or adjusting calibration should wear
specially tinted laser safety eyewear. For further information on laser safety
eyewear, see the Laser Safety Eyewear section of this manual.
To calibrate the laser:
1
Ensure that the keyswitch is in the
(off ) position.
2
Open the top protective covers of the laser console.
WARNING -
Opening the laser console protective covers will expose the
user to the laser resonator and possible laser radiation. Only Lumenis-certified
service technicians shall work inside the console.
3
On the CPU board (bottom PCB), slide switches 1 and 2 of SW2 to the open
position.
4
Turn the keyswitch to the
(on) position, slide SW2 switches 1 and 2 to
the closed position. The laser is now in calibration mode. The display flashes
an upper case “C”.
5
Select 1000 mW power, 50 ms exposure time, and a 50 ms interval time.
6
Attach a digital voltmeter across Main and Safe test points. Select DC volts,
auto-ranging.
7
Remove the CPU board and place a power meter in front of the fiber port.
8
Select ready mode, then depress the footswitch. Adjust the Main_Gain pot on
the Analog Board (top PCB) until the power meter reads 500 mW average or
1000 mW peak. Adjust the Safe_Gain pot until the voltmeter reads
0 V ±5 mV.
9
Turn the laser off then back on. Allow the laser to perform its self-test. The
laser should go into standby mode without any error codes displayed on the
control screen or remote control.
