Calibration System Calibration
This calibration is intended for the flows sensors in the breathing circuit, ventilator flow sensor, and
also inspiratory valve. The standard flow measurement device is used to calibrate the flow sensors
and inspiratory valve.
4.3.3.1 Calibration Procedures
NOTE: Make sure that the tubes are not leaking when connected.
NOTE: Do not move or press the tubes during calibration.
NOTE: When connecting calibration tubes, make sure that gas flows in the
correct direction, which is from the inspiration connector of the
breathing system, through high flow inlet of the anesthesia machine
calibration device, anesthesia machine calibration device, high flow
outlet of the anesthesia machine calibration device, and to the
expiration connector of the breathing system.
NOTE: Before calibration, make sure that no sensor or valve related technical
alarms occurred.
NOTE: During calibration, make sure that the drive gas pressure is enough.
Failure to do so may lead to calibration failure.
NOTE: You can select VT Plus for auto calibration. You can also select flow
calibration device which satisfies the accuracy requirement for manual
calibration.
NOTE: For calibration device with high flow channel and low flow channel,
flow channel switch over is required during auto or manual calibration.
Manual calibration is available in version 1.03.00 and higher.
4.3.3.2 Auto Calibration
Follow these steps to calibrate flow sensors.
1. Enter Standby.
2. Select Setup-> Service-> Calibration-> Flow Sensors to access the screen as shown.
