Slowly open the flow control valve until the recommended flow of
2 to 2.5 SCFH is established on the flow meter.
When the proper flow is achieved, make sure the relief valve is closed
by placing an object (e.g., your finger, if the gas is non-corrosive)
over the relief valve vent. Cover and uncover the relief valve vent and
verify that the flow meter shows no change in the flow rate. Keep the
relief valve closed during operation to minimize leakage in the
sample system.
