Deuterium Lamp Replacement
If the lamp burns out, or indicates falling energy after prolonged use, you should replace the lamp.
Replacement lamp assemblies (L6022728) are provided complete with pre-aligned mounts.

To replace the deuterium lamp:
1. Switch off the spectrometer and disconnect the line power cord.
If necessary, wait until the lamps and lamp compartment have cooled to room temperature.
2. Remove the lamp compartment cover by lifting vertically from the handhold on the rear of the
instrument, as shown in Figure 33.
3. Remove the lamp cover by undoing the two screws and lifting vertically.
4. Unplug the deuterium lamp connector by squeezing in the two lugs at each side of the
connector and carefully pulling the connector vertically upward.

5. Remove the lamp assembly from the bracket by slackening the thumbscrew and pulling the
lamp mount vertically upward.
Save the thumbscrew for use with the new lamp assembly.

finger marks on the lamp window.
