6. Disconnect the relevant gas inlet from the central outlet and let the gas leave the system
completely by opening the relevant flow control.
7. Close the flows and reconnect the gas inlet to the central outlet and recheck that the flow
indicated by the Test Device is 14 ± 0.5 l/min.
8. Proceed with next gas (step 1).
9. Refit covers and perform the needed calibrations according to the calibration tree.

Vaporizer calibration

Cassette pressure sensor calibration

This calibration calibrates the gain of the cassette pressure sensor. The calculation is linear and the
calibration factor is stored in EEPROM 52. The zero point of this sensor is calibrated frequently during
normal operation.
Equipment needed: Flow/pressure test device
Settings:
1. Enter test device high pressure range mode (mmHg).
2. Zero the test device. The reading on the test device should be 0.0.
3. Push the
