Calibrating the Cal Port, PDL
NOTE: Before this calibration is performed, the dye temperature should be approximately 39 °C.
1. Remove the SMA focusing mount from the rail assembly.
2. Type ‘CV’ from the C:\ prompt.
3. Set laser to the following settings
Wavelength = PDL
CV Voltage = 700
Pulse Width = 5 ms
Rep Rate = 1 Hz
4. Set NOVA II power meter to the following settings:
Range = 30W
Laser type = “VIS”
Average = 3 seconds
5. Verify that NOVA II power meter analog out is connected to laser J2.
6. Position the handpiece, so that is facing the Ophir detector head.
7. Press lowercase ‘e’ to allow the external shutter to open when the laser is fired.
8. Fire the laser adjusting the laser voltage until the NOVA II power meter reads
from 5W to 7W. Make note of the NOVA II power meter reading.
9. Make note of the laser voltage setting.
10. Move the handpiece to the cal port.
11. Set YAG cal port gain to 3.
12. Fire six shots into the cal port.
13. Verify cal port voltage reads from 0.50 to 1.25 volts.
If the cal port voltage is too low, increase the gain number (press lowercase ‘C’).
If the cal port voltage is too high, decrease the gain number (press uppercase ‘c’).
NOTE : Most gain is 0; least gain is 15.
14. Fire the laser six shots again, and read the cal port voltage from the CV screen.
15. Make note of the cal port voltage.
16. Make note of the cal port gain.
17. Press uppercase ‘U’, and then enter the NOVA II power meter reading from step 8.
18. Fire the laser again into the cal port, and then verify that the cal port energy measures
from 5.5W to 6.5W.
