Calibration System Calibration
NOTE: Set the machine to work in EFCS mode for flow calibration.
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.
Follow these steps to calibrate flow sensors.
1. Enter Standby.
2. Select Setup-> General-> Calibrate Flow Sensor to access the screen shown below.
