KION / KION-i
EXP and INSP pressure transducer
The calibration of the EXP and INSP pressure
transducers are made only if the PEEP transducer
calibration was completed successfully.

Offset 1:
9. All mushroom valves except MV1 and MV5 are
opened. Also the Fresh gas valve and PEEP valve
are opened to depressurize the system.
10. Offset adjustments of the EXP and INSP
pressure transducer E2-potentiometers until the
transducer value is close to zero (+15 cmH20
with PC1750C)
• The Tidal Volume display shows the target
value: 0 (102 with PC1750C, A/D value).
• The Exp. Tidal Volume display shows the
adjusting transducer value. Note that the
values displayed is converted from cmH20 to
the corresponding A/D-value.
• Fail if 64 attempts or 30 s has elapsed to
adjust pressure transducer E2-potentiometers
without being close to the target value.
Diagnostic 282/283, subdata ...00 0B.
Gain:
11. The PEEP valve is closed to enable the system to
be pressurized.
12. The system is pressurized to 6/7 of the pressure
level set by the user above (target value). 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 [(6/7 x
target value) -1 cmH2O] < PEEP < [(6/7 x
target value) + 10 cmH2O] for 4 s.
Diagnostic 286, subdata ...00 13.

13. The system pressure is increased to the pressure
level set by the user above (target value).
• Fail if the PEEP pressure is not within [target
value -1 cmH2O] < PEEP < [target value + 10
cmH2O] for 4 s.
Diagnostic 286, subdata ...00 15.
14. Gain adjustments of the EXP and INSP pressure
transducer E2-potentiometers until the transducer
value is close to the system pressure.
• The Tidal Volume display shows the system
pressure (target value). Note that the values
displayed are converted from cmH20 to the
corresponding A/D-value.
• The Exp. Tidal Volume display shows the
adjusting transducer value. Note that the
values displayed are converted from cmH20
to the corresponding A/D-value.
• Fail if 64 attempts or 30 s has elapsed to
adjust pressure transducer E2-potentiometers
without being close to the target value.
Diagnostic 282/283, subdata ...00 0F.
Offset 2:
15. All mushroom valves except MV4 are opened
Also the PEEP valve is opened to depressurize
the system.
16. The offset adjustments of the EXP and INSP
pressure transducer E2-potentiometers is
repeated, but with a negative offset (-25 cm H
or -10 cmH2O with PC1750C) to enable
measurement of negative pressures.
• The Tidal Volume display shows the target
value: 170 (A/D value).
• The Exp. Tidal Volume display shows the
adjusting transducer value. Note that the
values displayed is converted from cmH20 to
the corresponding A/D-value.
• Fail if 64 attempts or 30 s has elapsed to
adjust pressure transducer E2-potentiometers
without being close to the target value.
Diagnostic 282/283, subdata ...00 0D.
17. The results of the calibration of pressure
transducers 1, 2 and 3 are shown on the KION
Monitor with the number of the transducer
followed by Pass or Fail.
If the calibration of PEEP fails, the INSP and EXP
transducer calibration is not performed and no
Pass/Fail-text is shown for those transducers on
the KION Monitor.
