Large CO difference from
Reference
A large difference is detected between the
CO value and input Reference value.
Recalibrate the CO value.
Perform another Reference measurement.
Press Continue to proceed with user input Reference
value.
Calibration time has been
exceeded
The time between the completion of CO
averaging and user input Reference value
for calibration has exceeded system limits.
Perform a new CO calibration, ensuring a timely duration
between the completion of CO averaging, and the
acceptance of the Reference CO value.
Continuous Monitoring Has
Reached The 72 Hour Limit
