I2C-bus
Offset 1:
18. All mushroom valves except MV1 and MV5 are
opened. Also the Fresh gas valve and PEEP valve
are opened to depressurize the system.
• Fail if the PEEP pressure is not within
-1 cmH2O to 0.5 cmH2O for 4 s.
Diagnostic 286, subdata ...00 02.
19. Offset adjustments of the MAN pressure
transducer E2-potentiometers until the
transducer value is close to zero.

• The Tidal Volume display shows the target
value: 0.
• The Exp. Tidal Volume display shows the
adjusting transducer value (in 1/100 cmH2O).
• Fail if communication over the I2C-bus fails or
64 attempts or 30 s has elapsed to adjust
pressure transducer E2-potentiometers
without being close to the target value.
Diagnostic 285, subdata ...00 0A /...00 0B.
Gain:
20. The PEEP valve is closed to enable the system to
be pressurized.
21. The system is pressurized to +17 cmH2O. The
drive gas module regulates to a stable pressure
level with the already calibrated PEEP pressure
transducer as reference.
• Fail if the PEEP pressure is not within
+16 cmH2O to +37 cmH2O for 4 seconds.
Diagnostic 286, subdata ...00 07.
22. The system pressure is increased to +20 cmH2O.
• Fail if the PEEP pressure is not within
+19 cmH2O to +40 cmH2O for 4 s.
Diagnostic 286, subdata ...00 09.

23. Gain adjustments of the MAN pressure transducer
E2-potentiometers until transducer value is close
to the system pressure.
• The Tidal Volume display shows the system
pressure (target value).
• The Exp. Tidal Volume display shows the
adjusting transducer value (in 1/100 cmH2O)
• Fail if communication over the I2C-bus fails or
64 attempts or 30 s has elapsed to adjust
pressure transducer E2-potentiometers
without being close to the target value.
Diagnostic 285, subdata ...00 0E /..00 0F.
Offset 2:
24. All mushroom valves except MV4 are opened,
also the Expiratory valve is opened to
depressurize system.
• Fail if the PEEP pressure is not within
-1 cmH2O to 0.3 cmH2O for 4 s.
Diagnostic 286, subdata ...00 0D.
25. The offset adjustments of the MAN pressure
transducer E2-potentiometers is repeated, but
with a negative offset (-25 cm H
cmH2O with PC1750C) to enable measurement
of negative pressures.
• The Tidal Volume display shows the target
value: 2500 (1000 with PC1750C).
• The Exp. Tidal Volume display shows the
adjusting transducer value (in 1/100 cmH2O).
• Fail if communication over the I2C-bus fails or
64 attempts or 30 s has elapsed to adjust
pressure transducer E2-potentiometers
without being close to the target value.
Diagnostic 285, subdata ...00 0C /...00 0D.
26. The result of the calibration of MAN pressure
transducer is shown on the KION Monitor with
the number 4 followed by Pass or Fail.
