FID Fails Leakage Current Test

Possible causes

Procedure

26
A failed leakage current test usually indicates misassembly,
contamination, or a damaged part.
1
If you have just performed maintenance on the FID, first
verify that the detector was reassembled properly before
troubleshooting detector problems.
2
Replace the PTFE (FID) for contamination.
3
Make sure that the interconnect spring is not damaged, bent,
or dirty. The interconnect spring should be touching the
bottom of the collector. If the inteconnect spring is damaged,
bent, or dirty, call Agilent for service.
