You must have an auto cal card and RCU installed to use this menu
option.
Manually adjust the pressure and flow of your calibration gas (pressure of cali -
bration gas cylinders and flow into sensor) by cycling through the solenoid valves
on the RCU. No calibration or verification data is collected.
It is important that all calibration gases, as well as the sample gas,
flow through the analyzer at the same flow rate.

2. From the Calibrate Key menu, select Inject Cal Gas .
The following message displays, showing that the RCU has introduced the zero
gas to the sensor:
Adjust the pressure and flow for the zero gas to the desired levels. You will be
prompted to end the cycle.
3. Press Cancel to end the cycle.
If you specified a recovery time, the remaining recovery time displays.
