Mismatch
between selected

from HRS
Compare selected
calibration level
and applied

from HRS
Pressure signal
close to selected

Select correct
calibration level
Unable to zero Pa
pressure
Varying pressure Check that AO
transducer

opened to air
AO transducer

opened to air
Open AO

Too high or too
low pressure from
AO transducer
Check that AO
transducer is
placed on correct
level
AO transducer is
placed leveled
with patient
Reposition AO
transducer
Disturbance to Pa
pressure signal
Check Pa
pressure signal
for variations
No variation in Pa
pressure signal
Check according
to "Abnormal or
absent pressure
reading of Pa
pressure"
Abnormal or
absent pressure
reading of Pa
pressure
Bad contact in
AUX IN cable
connectors
Stress the actual
connection
mechanically
The Pa pressure
signal will remain
correct
Replace the
broken cable
Defective AUX IN
cable
Visually check the
cable
Strain relief intact,
no other damage
Replace the
broken cable
