Installation
Detector Electrical Connections
CAUTION: Do not use a wrench to tighten the SMC
connectors on the bias and electrometer cables.
Connections should be finger tight only.
1. Referring to Figure 9 as necessary, connect the BIAS cable to the top
electrode and the electrometer cable (ELECT) to the bottom electrode.
NOTE: If you have a GC-17 with the standard linear range FID electrom-
eter (Shimadzu P/N 221-43289-91), a 1000 Meg
Ω resistor must be soldered across R1 of the
electrometer board. To do this, first remove the
six cover screws and lift off the cover. Locate
R1 on the PC board and solder the resistor as
indicated at right.
2. Connect the high-voltage cable from the detector
to the pulse supply.
3. Connect the heater cable from the detector to “DET” on the wire panel of
the GC.
