This Information Applies To: All Agilent Spectroscopy Systems (AA50,55,240,280)
Issue: The deuterium (D2) lamp will need replacing if the lamp fails to light or it cannot match the hollow cathode element lamp energy in the Optimize page in SpectrAA Software. See Figure 1.

Steps to Follow:
Warning: Hot Surface and Eye Hazard. The deuterium lamp and its cover become very hot during operation. To prevent skin burns, allow the assembly to cool down before removing it.
|Warning: The deuterium lamp emits dangerous levels of UV radiation. To avoid eye and skin damage, NEVER interfere with the interlock switch, or attempt to operate the lamp unless it is mounted in the instrument.|

Tip: After installation, a new deuterium lamp must be aligned. See steps below.
To align a deuterium lamp:
|Tip: If both lamps are correctly aligned, the 2 scales (HC and D2) on Figure 1, will be approximately the same height.|
