6.20 Calibration reminders
When a sensor is due for a re-calibration, the calibration due reminder symbol ( ) will be
displayed flashing below the reading of the sensor that is due calibration, as shown in
Figure 13 .
This symbol will continue to flash until a calibration has been performed.
Figure 13 Carbon dioxide calibration due reminder
In the case of an oxygen sensor, the calibration due reminder will be cleared upon a successful
calibration. In the case of a carbon dioxide sensor, the reminder will only be cleared once a zero
and span calibration have been performed consecutively. See
the ‘Calibration’ section of this
manual for details of how to calibrate the sensors.
