9.4.UV Lamp Adjustment

1. Instrument should be running and warmed up for at least 20 minutes.

2. With instrument running, remove the six screws and the top cover (Rack Mount Configuration) or open front panel (NEMA Configuration.)

3. Locate the Reference UV Detector adjustment pot, PR3, on the Mainboard PCA (see Figure 9-1or Figure 9-2.)

4.Navigate the front panel menu to VIEW menu and scroll to REF display and press ENT. At this point there should be a scrolling display similar to “REF = XXXX MV.” See Section 7.2 for details on menu navigation.

5.While observing the REF value on the display, slowly turn the pot to adjust the value. The target adjustment range is as high as possible within the range of 800

1150 mV.

6.Locate the Measure UV Detector adjustment pot, PR4, on the mainboard PCA (see Figure 9-1or Figure 9-2.)

7.Navigate the front panel menu to VIEW menu and scroll to MEAS display and press ENT. At this point there should be a scrolling display similar to “MEAS = XXXX MV.” See Section 7.2 for details on menu navigation.

8.While observing the MEAS value on the display, slowly turn the pot to adjust the value. The target adjustment range is as high as possible within the range of 800

1150 mV.

9.If the required adjustment cannot be achieved by adjusting the UV Detector pot alone, then additional adjustment can be made by loosening the two UV lamp setscrews on the UV lamp housing (see Figure 9-1or Figure 9-2)and rotating the lamp. Rotate the lamp very slowly while observing the REF or MEAS value on the display. Make sure the lamp does not pull out and remains seated in the housing while it is being rotated. Re-tighten the two setscrews when a desired point has been reached.

10.If necessary, additional “fine tuning” can now be done with the UV Detector adjustment pots per steps 4-8.

11.Re-Install instrument cover and observe REF and MEAS values on display for a couple minutes to verify it does not drift out of the adjustment range.

9.5.UV Lamp Replacement

1. Disconnect power from the M465M.

2. Remove the six screws and the top cover (Rack Mount Configuration) or open front panel (NEMA Configuration.)

3. Loosen the two UV lamp setscrews on the UV lamp housing (see Figure 9-1or Figure 9-2.)

4.Unplug the lamp power cord from the connector labeled J18 on the mainboard PCA.

5.Carefully slide the lamp out of housing.

6.Install the new lamp, seating it in the lamp housing until it stops.

7.Re-tighten the two UV lamp setscrews.

8.Plug the lamp power cord into J18 on the mainboard PCA.
