1.10 Establishing a Gas Flow Through the Oxygen Cell (cont.)
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.
