KION / KION-i
Calibration
The Operating Manual describes how to perform the
semi-automatic Calibration. The KION Monitor path
to select Calibration is:
Menu / Monitor Setup / Biomed / Service / Calibration / KION
Calibration
or
Menu / KION / Service / KION Calibration (not applicable
for SC 9000)
Service Password is required to access the Service
menu.
The description below gives a more detailed
information about the Calibration. This information
can be used e. g. during troubleshooting of the KION
/ KION-i workstation.
Note: Before starting the Calibration, check that
there is no leakage in the workstation. Run the
leakage checks included in the PuC. Also check that
the Calibration manometer to be used is properly
calibrated.
Initialization
1. Calibration instructions are shown on the KION
Monitor.
2. CON sets the gas mixture to O
Check of control panel settings and of gas
supply
1. The system checks that the Upper Press. Limit
(UPL) knob is set between 60 and 80 cmH2O.
Diagnostic (288) will be shown in the Diagnostic
Log if UPL is not set correctly.
2. The system sets a flow of 0.5 l/min during 1.5 s
to be generated by the gas modules AIR (N
BP and DRIVE GAS for self-adjustment of the
flow in these gas modules.
3. The gas module AIR (N
of 30 l/min.
4. The system checks that the AIR supply pressure
is above 2.2 bar during 2.5 s.
5. If AIR supply pressure is above 2.2 bar during
2.5 s, then AIR will be used as the selected gas
for the Calibration.
6. The system sets a flow of 0.5 l/min during 1.5 s
to be generated by the gas module O
self-adjustment of the flow in this gas module.

7. If the AIR supply pressure drops below 2.2 bar
during the 2.5 s, the gas module O
generates a flow of 30 l/min.
8. If O is used, the system checks that the O
2
supply pressure is above 2.2 bar during 2.5 s.
9. If O supply pressure is above 2.2 bar during
2
2.5 s, then O will be used as the selected gas
2
for the Calibration.
10. Diagnostic (280) will be shown in the Diagnostic
Log if supply gas is missing.
If the UPL knob is not set correctly or if both AIR
supply and O supply Fails, the Calibration will not
2
start and the Calibration start-up screen will remain
on the KION monitor. Simultaneously, a caution
sound is activated.
Calibrating pressure transducers
During calibration, the pressure transducers are
identified as follows on the KION Monitor:
1 = EXP pressure transducer
2 = INSP pressure transducer
3 = PEEP pressure transducer
4 = MAN pressure transducer
