Calibration System Calibration
4.3.2 Flow Calibration (User)
NOTE: The flow sensors must be recalibrated after replacing or reinstalling the
flow sensors.
NOTE: This calibration is only intended for the user. A trained technician
should always perform the flow calibration in the service mode when a
calibration is required.
NOTE: The measurements performed by the flow sensors may be affected by
the environment where the sensors are used. After the sensors have
been used for a long time, great deviations may occur to the
measurement results and tidal volume control as well. This problem can
be fixed through flow sensor calibration.
NOTE: Before calibration, perform leak test of the breathing system in
mechanical ventilation mode first and make sure that the test is passed.
NOTE: During calibration, make sure that the drive gas pressure is kept within
specifications. Failure to do so may lead to calibration failure.
This calibration is only intended for the flow sensors in the breathing circuit. The inspiratory flow
sensor and expiratory flow sensor in the breathing system are calibrated through the built-in flow
measurement reference.
When great deviations (more than 9% compared with the setting value) occur to tidal volume
measurement due to sensor ageing or environmental factors or the user replaces flow sensors, you
need to re-calibrate flow sensors.
