8.2.2. Typical Sample Gas Flow Problems
8.2.2.1. FLOW IS ZERO
The unit displays a SAMPLE FLOW warning message on the front panel
display or the SAMPLE FLOW test function reports a zero or very low flow
rate.
Confirm that the sample pump is operating (turning). If not, use an AC voltmeter
to make sure that power is being supplied to the pump. If no power is present at
the electrical leads of the pump.
1. If AC power is being supplied to the pump, but it is not turning, replace the
pump.
2. If the pump is operating but the unit reports no gas flow, perform a flow check
as described in Section 6.3.4.
3. If no independent flow meter is available:

Disconnect the gas lines from both the sample inlet and the exhaust
outlet on the rear panel of the instrument.

Make sure that the unit is in basic SAMPLE Mode.

Place a finger over an Exhaust outlet on the rear panel of the instrument.
