1. Open the atmospheric vent header shut-off valve for the combined
sample bypass and measurement cell effluent from the SCS, if
applicable.
2. Open the sample supply port shut-off valve and slowly open the
pressure regulator (turning knob clockwise).
3. Set the inlet pressure regulator on the panel to a setting that will
maintain the specified flow meter settings and provide good control
using the analyzer and bypass flow control valves.
4. Open the bypass flow meter control valve to establish sample flow
from the sample probe and set the flow meter to the specified value.

1. Open the sample flow meter control valve to approximately the
specified flow.
2. If required, adjust the pressure regulator at the field pressure
reducing station to the specified setpoint.
3. Adjust the sample flow meter control valve to the specified flow.
4. Confirm the sample flow and pressure setpoints and readjust the
control valves and pressure regulator to the specified setpoints, if
necessary.
Flow meter pressure should never exceed 100 PSIG or a gas
temperature over 100
F. Serious property damage and/or great
personal injury could occur as the result of a misused meter or
meter installed in an unsuitable application.
Do not exceed 10 PSIG at any time in the cell. Refer to Appendix A
for analyzer specifications.
The adjustment setpoints of the analyzer flow meter and pressure
regulator will be interactive and may require multiple adjustments
until the final setpoints are obtained.
The analyzer system has been designed for the sample flow rate
specified. A lower than specified sample flow rate may adversely
affect analyzer performance. If you are unable to attain the
specified sample flow rate, refer to “Service Contact” on page
B-22 for service information.
