8.7 Leak Check Procedure

If a leak checker is not available, it is possible to leak check the instrument using the M200AU's pump plus a shut-off valve.

1.Turn off instrument power and pump power.

2.Cap the sample inlet port, ozone generator air inlet, and zero air inlet (if Z/S valve option present).

3.Insert a shut-off valve between the sample pump and the vacuum manifold at the rear of the instrument.

4.Turn on the sample pump and set the TEST function to RCEL, which measures the reaction cell pressure. Close the shutoff valve and monitor the cell pressure. The pressure should not drop more than 1"-Hg (0.5psi) in 5 minutes. If there is a leak, it is not possible by this method to tell where it is located. You can locate the leak by using a pressure leak checker described below.

5.The sensor module is equipped with a fitting at the top of housing near the heat sink fins. This fitting can be pressurized and the sensor checked for leaks. The leak-down rate is the same as above.

If you have a leak checker:

1.Turn off instrument power and pump power.

2.Disconnect pump at rear panel. Cap the sample inlet port, ozone generator air inlet, and zero air inlet (if Z/S valve option present) and connect the leak checker to the exhaust port.

CAUTION

Pressure must be less than 15 psi.
