Measure Vent Flow (MV)

You will need an accurate flow meter (Alltech Digital Flow Check™ Flowmeter or equivalent) for
this measurement.
To measure the MV vent flow, proceed as follows:
(1) Attach a flow meter to the vent output on the left side of the Analyzer marked "MV".
(2) The flow should measure 12-18 cc/min.
