• Make sure flows are acceptable for ignition.
• Heat the detector to operating temperature or 300 °C.
Test for the detector. Read the Test Details screen then press Start Test.
detector's output from the drop-down list, then touch Add.
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.
