3) Connect the calibration gas to either of the instrument's sample
port using a quick disconnect fitting. Use a blank quick
disconnect fitting on the other port to open the seal.
Always connect the vent fitting first followed by the source
fitting.
The analyzer is insensitive to flow rate, however for calibration,
use a flow rate similar to the sample flow you will be using. If
the flow rate will vary or is unknown, use a flowrate between
1–2 liters per minute. Allow sample to flow for several minutes
to flush the sample line. Watch the output of the meter for the
reading to stabilize.
4) Unlock and adjust the span control until the meter pointer is in
coincidence with the concentration of the calibration gas.
Note: Be sure that you relock the control after the adjustment is made.
5) Immediately after step 4 has been accomplished, disconnect the
calibration source gas fitting at the analyzer sample port, and
plug in either the sample or a source of zero gas.
Always disconnect the source fitting first, immediately followed by
the vent fitting.
