pump by-pass valve to limit the maximum flow rate to full scale on the flowmeter with the flowmeter valve fully open. Adjust the analyzer flow control valve (flowmeter valve) to a flow-rate of approximately 2 SCFH). Select Span and verify that the span and Sample gas are at different pres- sures. The calibration accuracy will be adversely affected if the Span and Sample gases are at differing pressures.

If the span gas is provided from pressurized source, a control valve must be added between the analyzer and the span gas source. This valve is used to adjust the span flow rate to match the sample flow rate. Do not adjust the span flow rate with the flow control valve located on the analyzer for units with vacuum service options.

3.5Installation Checklist

Before connecting the instrument to the power source and turning it on, make sure you have:

•Correctly installed the Sample and Exhaust gas lines

•Opened the isolation valves

•Checked for leaks

•Set the sample pressure to 5–10 psig, nominal (for non-vacuum service units)

•Set the flow

Once the above checks have been made, you can connect to the power source. The instrument is now ready for operation.
