– Calibrate O2-sensor with 21 Vol.% O2
– Calibrate flow sensor
– Perform Ventilator start up test
– more
The following can be realized under »more«:
–O2 sensor calibration with 100% O2 by volume,
– linearity check of the O2 sensor and
– calibration of the CO2 sensor.
The significance of the symbols is as before:
? = Enquires whether an action has been performed
or a setting made.
