Background offset checks
1. If lit, turn the FPD flame off.
2. Display the signal output to determine flame-off background offset. A
stable value of < 40 display units is acceptable.
3. Ignite the flame. You should see an increase in detector output to a stable
value.
If not, confirm ignition by holding a mirror or shiny surface near the
aluminum exhaust tube, with the rubber drip tube removed, and observing
condensation if the flame is lit.
If the flame has not ignited, see “Flame ignition problems” on page 208.
