Figure 5-2. Replacing a Halogen Lamp
6. Insert the lamp’s electrical supply cable connector into the appropriate socket. The deuterium lamp
has a three-pole plug, the halogen lamp a two-pole one. It is impossible to plug a lamp’s power
supply into the wrong socket.
7. Put the lid back on from the top of the instrument and fasten the screws of the cover.
8. Install the dummy cell, set the wavelength to 240 nm, and record the signal and reference values as
a reference to track the lamp output and flow cell cleanliness.
9. If you are not changing the lamp type (i.e. you replaced a deuterium lamp with a new deuterium
lamp or a halogen lamp with a new halogen lamp), then the QuadTec Setup menu remains
unchanged, but the lamp working hours should be reset (see page 4-3).
If you changed lamp types (i.e., from deuterium to halogen or halogen to deuterium), follow the
procedure below.
Changing Between Lamp Types
If you changed lamp types (i.e., from deuterium to halogen or halogen to deuterium), then the QuadTec
Setup menu must be modified to reflect the change in lamp type.
1. Turn on the detector and when the screen displays the firmware version (e.g. v1.5), immediately
press the green arrow keys in the following sequence: Up/Down/Up. This loads the Extended Setup
application.
2. After initialization and calibration are complete, select the Setup menu by pressing the right green
arrow key until the cursor is blinking next to Setup on right side of LCD. Hold the arrow key for a few
seconds and the Extended Setup menu will appear.
