CHANGING THE UV WAVELENGTH
A UV Crosslinker is purchased with shortwave, longwave or midrange tubes. However, if user
requirements and applications change, the Crosslinkers provide you with the unique ability to change
the ultraviolet wavelength and recalibrate the UV sensor and microprocessor to the new UV
wavelength. This is accomplished by purchasing FIVE tubes of the NEW UV wavelength and the proper
UVP calibration sensor.

UV Wavelength Calibration Procedure
1. After disconnecting the unit from the electrical supply, install the FIVE NEW WAVELENGTH
Tubes as directed. (Section - Changing tubes).
2.
Plug the corresponding UV calibration sensor into the TOP HOLE just inside of the door at the
upper right.
3. Place the UV calibration sensor in the middle of the floor of the exposure chamber.
4.
Close the Crosslinker door.
5.
Invoke the calibration mode of the Crosslinker by pushing/holding down STOP on the tactile touch
pad and turning the power to the unit ON.
6.
A sequence of tones will be heard from the Crosslinker and a 180-second count will display on
the LCD when the calibration procedure has started.
7.
No calibration occurs during this 180-second period. This period allows a UV tube warm-up and
stabilization period.
8.
Upon completion of the 180-second period, measurements are automatically made with the UV
calibration sensor and the Crosslinker sensor. These measurements are compared to limits of
acceptability and/or if sensor operation is within range.
9.
If sensor readings are unacceptable, an error code (01, 02, 03 or 04) will flash on the LCD Press
any key to stop.
10. Check all connections and redo calibration. If the same error message appears, call UVP.
11. The previous calibrated operation of the Crosslinker will continue following any unsuccessful
recalibration. Replace the new UV wavelength tubes with the previously removed old wavelength
tubes.
12. Successful recalibration to the NEW UV wavelength changes the values in the microprocessor
and numeric setting value is displayed on the LCD. To return to original or another wavelength
the proper UV calibration sensor is needed.
