Sub data:
Fault: The gain calibration of the fresh flow gas transducer failed.
CON is responsible for calibration of this transducer.
Description: The fresh gas flow from the AIR/N2O or O2 gas modules are 5 l/min
(target value) during the gain calibration of the fresh gas flow transducer E2-
potentiometer. The fresh gas flow transducers E2-potentiometers are adjusted during
calibration until the measured flow is close to the target value.
The acceptance criteria for successful gain calibration is that the measured flow do not
differ more than 0.5% from the target value. If not, this diagnostic log is written.
Displays on Control panel:
The Tidal Volume display shows the target value: 833 (=5 l/min).
The Exp. Tidal Volume display shows the measured flow value by the fresh gas flow
transducer (1/10 ml/s).
What to do:
1. Replace the fresh gas flow transducer.
2. Replace PC 1748/PC 1797 Fresh gas flow.
3. Replace the gas module:
- If Air supply gas is connected: AIR/N2O gas module
- If Air supply gas is not connected: O2 gas module.
Fault: The calibration of the expiratory flow transducer failed during the "Checking flow
transducers" test in the PuC.
Refer to information regarding "Checking flow transducers" in chapter "Service
procedures", section "Pre-use check".
