Gas Measurement Calibration Check
To check the calibration of the CO
2
gas measurement:
Step
1
Ensure that the CO
2
module is not in Standby mode (when the monitor is
in Display Waveform mode, Standby is displayed in the CO2 waveform
pane).
If necessary, turn on the CO
2
module by opening the CO2 Menu and
setting CO2 On/Standby: to On.
2
Open the Maintenance options in the Diagnostics Menu. See “Accessing the
Diagnostics Menu and Maintenance Options” on page 3-6.
3
Select the CO2 Test button.
The CO2 Test menu appears.
4
Connect one end of the sampling line to the CO
2
inlet on the monitor and
leave the other end unconnected.
5
In the CO2 Test menu, select Start Calibration Check.
A message to connect the gas to the CO
2
module appears.
6
Connect the other end of the sampling line to the gas controller
equipment inlet with a 5% gas concentration.
7
Open the valve on the gas controller equipment to allow 5% CO
2
gas to
flow into the monitor.
8
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 Test window displays a message. For example:
CO2 calibration check successful. CO2 rate: 5.1.
9
If the module is not in calibration, an error message appears. Calibrate the
module. See “Calibrating the Sidestream CO
2
Module” on page 3-13.
