UV CROSSLINKERS UVP
7. 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.
TUBE P/N WAVELENGTH UVP CALIBRATION SENSOR P/N
34-0006-01 365 nm Longwave 97-0016-02 UVX-36 Longwave
34-0042-01 302 nm Midrange 97-0016-04 UVX-31 Midrange

UV Wavelength Calibration Procedure
1. After disconnecting the unit from the electrical supply, install the FIVE NEW
WAVELENGTH Tubes as directed in Section 9A. (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 touchpad 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 LED 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 LED
Press any key to stop.

10. Check all connections and redo calibration. If the same error message appears, call UVP.
