Test Test description * Recommended action if the test fails
Pressure transducer
test
Calibrates and checks the inspiratory
and expiratory pressure transducers.
The new zero value for the pressure
transducers may not differ more than
±6 cm H
2
O from factory calibration.
With the inspiratory pressure
transducers used as a reference, a new
gain factor is set for the expiratory
pressure transducer. The new gain
factor may not differ more than ±5%
from factory calibration.
During this test, the different
subsystems concerned are compared.
The difference between the sub-
systems must not be more than
±1 cm H
2
O at 60 cm H
2
O.
Expiratory valve coil test. Measures
offset and gain in the valve coil.
(BRE + MON)
Check that System SW V1.03.01 (or
later) is installed. Update System SW if
required.
Check the ‘Test results’-log in the
‘More detailed’ mode. (FSS)
If ‘Pressure transducer test’ failed:
1. Check the expiratory cassette:
• If possible, replace the
expiratory cassette and check if
the new cassette is accepted by
the Pre-use check.
• If the new cassette was
accepted by the Pre-use check,
the fault was located to the
cassette.
The fail with the old cassette
may in this case be due to water
collected at the pressure
transducer filter inside the
cassette. Dry the old cassette
properly.
2. Check/replace PC 1781 Pressure
transducer (Insp. and Exp.).
To locate the faulty pressure
transducer, replace one transducer
at a time.
3. Replace PC 1771 Control.
4. Replace PC 1772 Monitoring.
If ‘Expiration valve test’ failed:
1. Check the expiratory cassette:
• If possible, replace the
expiratory cassette and check if
the new cassette is accepted by
the Pre-use check.
• If the new cassette was
accepted by the Pre-use check,
the fault was located to the
cassette. To repair the old
cassette, check that the
expiratory valve membrane is
clean and correctly seated in
the cassette. Replace the
membrane if required.
2. Replace the Expiratory valve coil.
