Calibrating the Sidestream CO

Module
Caution Because the monitor uses the current date and time as the calibration date and time,
ensure that the system date and time is set correctly.
Note — The monitor always displays the CO
2
module’s operating (usage) time in the
CO2 Test menu.
To calibrate the CO

Connect the other end of the sampling line to the gas controller
equipment inlet with a 5% gas concentration.

Open the valve on the gas controller equipment to allow 5% CO
2
gas to
flow into the module.
11
Select OK in the confirmation window to begin checking the calibration.
Note — The calibration check can take up to one minute to complete. The
monitor checks the calibration and when the calibration check completes,
the CO2 Module Maintenance window displays a message. For example:
CO2 calibration check successful. CO2 rate: 5.1.

If the module is not in calibration, an error message appears. Calibrate the
module. See “Calibrating the Sidestream CO
