Agent Pressure Sensor Calibration - Datex-Ohmeda Anesthesia Delivery Unit S/5 Technical Reference Manual

Agent pressure sensor calibration

This calibration calibrates the factors used in the calculation for compensating the zero signal change
caused by the static pressure and the magnetic effects of the valves in the vaporizer valve block. The
calculation is linear and the calibration factors are stored in EEPROM 46-47.
Equipment needed: Flow and pressure test device,
Settings:
1. Enter Test Device low pressure range mode (mmHg).
2. Zero the Test Device. The reading on the Test Device should be 0.0.
3. Disconnect fresh gas hose from fresh gas outlet.
4. Remove the vaporizer cassette.
5. Push
Vaporizer - Agent pressure.
