1. Set up.
a. Open the front door and remove the top (external) cover including the inside laser head cover.
b. Disable the AUTOCALIBRATION by moving the calibration switch (SW3) on the Controller PCB to
the left.
2. Turn the laser on.
3. Access SERVICE MODE by moving sliding the service switch (SW2) on the Controller PCB to the left.
4. Initialize the NVRAM.
On the first service screen, depress the INIT NVRAM button and hold until the second tone is heard.
This clears and initializes the battery back-up memory, then loads the default values.
5. Set the laser to the following parameters:
a. Voltage 800V
Pulse Rate 10 Hz
Lamp Energy 45J
b. Turn on the first laser channel (all other laser channels should be OFF).
6. Attach a Power Calibration Fiber (P/N 0623-973-01) and turn ON the aiming laser.
Direct the fiber output toward the external power meter. The aiming beam should approximately
10mm in diameter.
7. Place the laser in READY mode.
8. Depress the footswitch and fire the laser.
Adjust the LAMP ENERGY until 6 Watts is delivered out of the fiber.
9. Setting the Differential and Gain amplifiers.
a. Attach oscilloscope probes to TP15 (SDIF) and GND on the Controller PCB, and adjust potentiome-
ter SGAIN (R4) on the Optics Bench PCB until the signal amplitude is 4.0 ±0.1 VDC.
