Test Expected Test Results
What to record on
service record
Pressure Transducer Accuracy Test X1 = difference between the pressure on
the monitor and on the simulator
Difference less than or equal to 5
mmHg (0.7 kPa)
PN:P/X1/X2/X3/X4/X5
or
PN:F/X1/X2/X3/X4/X5
P = passed, F = failed
Pneumatic Leakage Test X2 = difference between the pressure at
the start (P1) and after one minute (P2)
Difference less than or equal to 6
mmHg (0.8 kPa)
Inflation Rate Test X3 = number of seconds for the monitor
to inflate
Rate between 1 and 6 seconds
Over-Pressure Test X4 = peak value
Peak value between 270 and 330 mmHg
(36 kPa and 44 kPa)
Deflation Rate Test X5 = mmHg (kPa) per second to deflate
1.8 mmHg/s to 4.8 mmhg/s
