Calibration | 5-7
The system will begin the automatic calibration and will notify you how
long the span gas will be applied to the sensor from the RCU:
Zero Gas xx:xx
System Calibrating
During this time, the RCU has switched the solenoid valves and has intro-
duced the zero gas to the sensor.
Then the system will display the recovery time remaining:
Recovery xx:xx
The system then returns to monitoring process readings, and the calibra-
tion is complete. You can view the results of the last calibration using the
Cal/Verify Data menu option from the Calibrate key menu.
