To Check the FID Leakage Current
1 Load the analytical method.
• Make sure flows are acceptable for ignition.
• Heat the detector to operating temperature or 300 °C.
2 Perform a Leakage Current Test: Diagnostics > Diagnostics Tests > select Leakage Current
Test for the detector. Read the Test Details screen then press Start Test.
3 Turn off the FID flame.
4 Show the detector output signal in Status. Go to Home > Status listing > +Add. Select the
detector’s output from the drop-down list, then touch Add.
5 Verify that the output is stable and < 1.0 pA.
If the output is unstable or > 1.0 pA, turn off the GC and check for proper assembly of the
upper FID parts and contamination. If this contamination is confined to the detector,
bakeout the FID. See “To Bakeout the FID” on page 161.
6 Turn on the flame.
