8.8 UV Lamp Power Supply Adjustment

Adjust the drive power of the lamp power supply as follows:
1. Remove the cover of the lamp power supply. Attach a DVM across TP7 and TP10, and
adjust the pot (VR1) until the DVM reads 20 volts ± 1 volt.
2. Adjust the positioning of the source lamp, as follows:
a. At the front panel of the instrument, Press the TEST key until O
displayed.
b. Loosen the lamp retaining thumb-screw and rotate the lamp until the O
display is 4500 mV ± 320 mV. Re-tighten the thumb-screw. (Note that the full range of
lamp adjustment can be achieved within ¼ revolution of the lamp. Note also that the O
REF display is updated approximately once every six seconds, and slow rotation of the
lamp is needed for proper adjustment.)
