To Measure FID Baseline Output
1 With the column installed, load your checkout method.
2 Set the oven temperature to 35 °C.
3 Press [Front Det] or [Back Det], then scroll to Output.
4 When the flame is lit and the GC is ready, verify that the
output is stable and < 20 pA (this may take some time).
5 If the output is not stable or > 20 pA, the system or gas may
be contaminated. If this contamination is isolated to the
detector, bakeout the FID.
