To calibrate the analyzer:
1.Shut the sample gas off, disconnect the sample in line and connect the the span gas to the sample inlet. Allow the span gas to flow through the system. Adjust the span gas flow rate until the flowmeter float is centered in the flowmeter reference indicator. Note the reading of the external recorder or meter.
2.Turn the range selector switch to the range which encompases the oxygen concentration of the span gas. The meter or recorder should move upscale and indicate the exact concentration of oxygen in the span gas.
3.If the external recorder/meter does not indicate the proper amount of oxygen, adjust the span dial until it does.
4.After the recorder or meter has stabilized on the proper readout, turn off the span gas flow, disconnect the span gas, reconnect the sample gas and establish the proper flow.
