... 00 0A CAL_EXP_OFFSET_MEA_FAIL
... 00 0B CAL_EXP_GAIN_MEA_FAIL
Fault: The offset calibration of the Exp. flow transducer failed.
MEA is responsible for calibration of this transducer.
Description: The flow is zero (target value) during offset calibration of the Exp. flow
transducer E2-potentiometer. The Exp. flow transducers E2-potentiometers are
adjusted during calibration until the measured flow is close to the target value.
Refer to chapter about Exp. flow transducer calibration during PUC.
Displays on Control panel:
The Tidal Volume display shows the target value: 0
The Exp. Tidal Volume display shows the measured flow by the Exp. flow transducer.
What to do:
1. Replace the Exp. flow transducer.
2. Replace PC 1750 Transducer.
3. Check the electric connection to the flow transducer (N126/P126).
Fault: The gain calibration of the Exp. flow transducer failed.
MEA is responsible for calibration of this transducer.
Description: The fresh gas flow is 14 l/m during 3 seconds (=700 ml). Several
attempts (max 14) when calibrating the gain of the Exp flow transducer.
The Exp. flow transducers E2-potentiometers are adjusted on every attempt until the
measured volume is close to the target value (700 ml). Between every attempt the
Exp. flow transducer is zeroed.
After 14 attempts, if the calculated volume is not close to 700 ml, this diagnostic log is
written.
Displays on Control panel:
The Tidal Volume display shows the target value: 700
The Exp. Tidal Volume display shows the measured volume (ml) after each attempt .
What to do:
1. Replace the Exp. flow transducer.
2. Replace PC 1750 Transducer.
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.
4. Check the electric connection to the flow transducer (N126/P126).
