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

module’s operating (usage) time in the
CO2 Test menu.
To calibrate the CO

Connect one end of the sampling line (if not already connected) to the
CO

inlet on the monitor and leave the other end unconnected.

In the CO2 Test menu, select Start Calibration.
A confirmation window appears telling you to connect the gas to the CO
2
module.

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

gas to
flow into the monitor.
