Observe the ignitor plug though the FID chimney. The small
hole should glow during ignition sequence.
If the test fails, check for the following possible causes:
• The ignitor may be bad; replace the ignitor. (See
Maintenance on the FID Collector
• Detector temperature is set to < 150 °C. Agilent recommends
operating the FID at > 300 °C.
• The ignitor is not making a good connection to the ground:
• The ignitor must be tightly screwed into the FID castle
assembly.
• The three T-20 Torx screws that hold the collector
assembly in place must be tight.
