8.4.5 Zero the Sensor
Zeroing the sensor aims to eliminate the effect of baseline drift on the readings during the
measurement so as to ensure measurement accuracy.
For microstream CO2 module, a zero calibration is carried out automatically when necessary.
You can also start a manual zero calibration when deemed necessary. To manually start a zero
calibration, enter the [Gas Module Setup >>] menu and then select [Zero]. You do not need
to disconnect the sensor from the breathing system when performing the zeroing.
8.4.6 Calibrate the Sensor
For microstream CO2 module, a calibration should be performed once a year or when the
measured value has a great deviation.
