Calibration procedures are initiated at the Calibrate menu� Refer to local regulations
for calibration requirements� Calibrate the monitor at least once a year to maintain

This screen is visible only on models with the CO
password has been entered� Calibration cannot be performed if Automatic Baseline
is enabled, as it is by default (see Configure > Configure Outputs > Automatic
Baseline above)�
The top line shows the current state of the gas sensor� Possible values include:
• normal
• in base cal
• base cal pass
• base cal fail
• in fault
The gas sensor must be in the "normal" state for a calibration to be performed� The
second line shows the current CO
line is a button that facilitates setting the target or actual concentration� Leave this
at zero if pure nitrogen is being used for calibration�
The fourth line is the [Base Cal Now] button� This causes the sensor to execute a
calibration function to make its output match the target concentration� Calibration
takes about 15 seconds� Another calibration cannot be performed without leaving
and returning to this screen�
