Installing and Configuring the FID Logic Board
Agilent 6890 GC (units without EPC)
The D3 uses the electrometer portion of
the Agilent FID logic board, which must be
configured to ignore the ignitor circuit.
1. Plug the FID logic board into the GC
main board at the location corresponding
to the detector mounting position (front
or rear) which you intend for the D3.
(Refer to the GC manual as required.)
Tighten the detector card screw.
