... 00 0B CAL_PRS_OFFSET_FAIL
... 00 0F CAL_PRS_GAIN_FAIL
Fault: The first offset calibration of the INSP pressure transducer failed.
Description: The system pressure is zero during offset calibration of the INSP
pressure transducer E2-potentiometer. The INSP pressure transducers E2-
potentiometers are adjusted during calibration until the transducer value is close to
zero (+15cmH20 with PC1750C).
Displays on Control panel:
The Tidal Volume display shows the target value: 0 (102 if PC1750C). A/D value.
The Exp. Tidal Volume display shows the adjusting transducer value.
Values displayed is converted from cmH20 to corresponding A/D-value.
What to do:
1. Replace PC 1750 Transducer.
2. Replace PC 1737 Measuring.
Fault The gain calibration of the INSP pressure transducer failed.
Description: The drive gas regulates a stable system pressure of 40-50 cmH2O, with
the already calibrated PEEP pressure transducer as reference, during gain calibration
of the INSP pressure transducer.
The INSP transducers E2-potentiometers are adjusted during calibration until the
transducer value is close to system pressure.
Displays on Control panel:
The Fresh Gas Flow digit display shows the pressure measured by the INSP pressure
transducer until a stable pressure is reached.
The Preset O2 Conc. digit display shows the pressure measured by the EXP pressure
transducer until a stable pressure is reached.
The Minute Volume display shows the pressure measured by the PEEP- pressure
transducer until a stable pressure is reached.
The Tidal Volume display shows the system pressure (target value).
Values displayed is converted from cmH20 to corresponding A/D-value.
The Exp. Tidal Volume display shows the adjusting transducer value.
Values displayed is converted from cmH20 to corresponding A/D-value.
What to do:
1. Check for leakage in the system
2. Replace PC 1750 Transducer.
3. Replace PC 1737 Measuring.
4. Replace the Drive gas module.
