If you have a pump on your system you will be prompted to adjust
the flow rate so the system can calibrate the pressure sensor. Leave the
calibration flow on. Adjust the flow rate to the same value as you did
for the span and zero gases.
8. Press Enter when you have adjusted the flow rate to 150 sccm (± 5
sccm). The pump affects the flow rate and the flow rate must remain
constant. The flow rate must be adjusted again to this constant flow
rate when the pump is turned on. At this point, a five-minute calibra-
tion period will occur.
The system will display the recovery time remaining:
After the recovery time has elapsed, the system returns to monitoring
process readings. After calibration, ensure that the flow rate of your pro-
cess gas stays at 150 sccm (± 5 sccm). If not, adjust the flow using the flow
knob.
If you want the pump on, you will have to turn it back on. To turn the

pump back on, see the "pump" section in Chapter 4.
