Single Gas Calibration
auto Calibrate

Enter the calibration gas value to match the zero calibration gas cylinder you are using to
calibrate your system.

Define how long you want the calibration gas to flow through the sensor. Remember
that with an auto calibration, the RCU automatically shuts down the zero calibration gas
based on the calibration gas duration time you specify. Be sure to allow enough time for
the gas to stabilize. You may want to use the
inject Cal Gases
option from the
Calibrate
menu to determine how long it takes for the gas from the RCU to reach the sensor and
stabilize, and then use this time.

Define a time period for the system to recover from reading the calibration gas value to
reading process gases.
1. From the Calibrate Key menu, select Initiate Cal .
2. Select Continue Cal to continue, or Abort Cal to cancel the calibration and
avoid recovery time. Pressing Cancel acts the same as Abort Cal .
The following message displays:
During this time, the RCU has switched the solenoid valves and has introduced
the zero gas to the sensor.
The remaining recovery time displays:
The system returns to monitoring process readings and the calibration is com-
plete.
You can view the results of the last calibration by selecting Cal/
Verify Data from the Calibrate Key menu.
