3. Slowly open the flow control valve until the recommended flow of 2 to 2.5 SCFH is established on the
flow meter.
4. 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.
