CALIBRATION for 3000 WATT UNITS
This page will show you how to
calibrate your equipment if necessary.
A new lamp should be used as this
procedure will reset the “LAMP TEST”
feature. You will want to measure your
lamp’s UV as compared to a new lamp.
The Integrator was calibrated at the factory
and will not need calibration unless the
Lamp Test with a new lamp does not show
a number between 80 and 120.
TO RECALIBRATE THE AdVantage

20 INTEGRATOR:
 Press ‘LAMP ON’. Wait about 2 minutes for the lamp temperature to stabilize. Make
every effort to maintain the lamp’s temperature throughout the entire procedure.
 Press ‘RESET’ to turn the lamp off.
 Press ‘LAMP ON’ 2 times.
 Take note of the number to which the read out scrolls.
 Press ‘RESET’ to turn the lamp off.
 Locate the photosensor by removing the two screws securing the front panel to the main
frame of the unit, and allowing the panel to rest on its bottom hinge.

The sensor can be rotated by hand, but its holding screw many need loosening.

A slight rotation of the sensor greatly affects calibration.
 Rotate the photosensor based on the number noted above. Aim for the range 90-110.
• If the number is low, you will need to slightly rotate the photosensor toward the light
source to see more light.
• If it is high, you will need to slightly rotate the photosensor away from the light
source to see less light.
WARNING: Light leaks with panel open. Always
hold the panel CLOSED before pressing ‘LAMP ON’.
 Repeat pressing ‘LAMP ON’ 2 times to see where the read out stops. If the number is
not within range, rotate the photosensor as necessary and repeat the procedure.
 Once the read out stops at a number in range, allow the lamp temperature to stabilize,
and perform the following steps in rapid succession.
 Scroll to Program C; then press and hold ‘EXP SET’.
 While holding ‘EXP SET’, press ‘START’.
 Release ‘EXP SET’ and ‘START’. The counter will increase to a number and hold.
The number should be between 90 and 110, just as it was in the step above.
 Press ‘START’. The display will read “CAL”.
 Calibration is now complete. Press ‘RESET’ to resume normal operation.
