10.2 Performance Problems

When the response from a span check is outside the control limits, the cause for the drift should be determined, and corrective action should be taken. Some of the causes for drift are listed below:

1.Fluctuations in flow. Such as leaks or plugged orifices.

2.Lack of preventive maintenance.

3.Change in zero air source.

4.Change in span gas concentration.

A.Zero air or ambient air leaking into span gas line.

B.Cal gas tank exhaustion.

C.Dirty particulate filter.

10.2.1 AC Power Check

1.Check that power is present at main line power input. Verify that correct voltage and frequency is present.

2.Check that the unit is plugged into a good socket. Analyzer must have 3-wire safety power input.

3.Check circuit breaker. Circuit breaker is part of the front panel power switch. It is set each time the instrument power is turned on. If there is an internal short causing a trip, the switch will automatically return to the OFF position when an attempt is made to turn it on.
