Removing & Replacing The Tungsten Lamp
To remove the tungsten lamp, pull the metal clip away from the tip of the lamp and
carefully pull the lamp to remove.
To insert the new lamp, pull the metal clip away from the housing to provide space
for the new lamp to be inserted and carefully insert the pins of the lamp into the
lamp housing. When inserted in the housing carefully place the metal clip on the tip
of the lamp.
Note: When replacing a tungsten lamp, the lamp envelope must not be touched. If
the envelope is touched during installation the lamp must be thoroughly cleaned with
a light cloth.
Removing & Replacing The Deuterium Lamp
The Deuterium lamp is removed by carefully pulling the lamp upwards. To insert the
new lamp, line up the lamp pins with the holes in the lamp housing and push into
place. The Deuterium lamp can only be inserted in the correct position.
Note: After installation the Deuterium lamp must be thoroughly cleaned with a light
cloth to remove any marks.
Replacing The Lamp Chamber Lid
After the new lamp has been installed the lamp chamber lid should be replaced and
screwed in place. The instrument will now be ready to use.
Note: A new baseline should always be measured after installing a lamp. This
procedure is described in "8.6. Instrument Settings" on page 18. The baseline
should only be collected after the lamp has warmed up sufficiently (at least 30
minutes).

With new lamps installed it is necessary to reset the lamp life on the software, this
is done as follows:
From the main page, select Settings followed by Instrument Settings.

Reset Lamp Life icon to reset the lamp life information for the desired lamp. The
icons are detailed in the Table of Icons section.

Only users with Administrator privileges are capable of resetting lamp life
information. For PC variants, lamp life can be reset using Datrys software. See
Datrys user manual or on-line help for more details.
