Test Expected Test Results
Barometric Pres- X1 = difference between the reference pressure and the
sure Check measured ambient pressure displayed on the M3046A
(X1<12 mmHg)
Leakage Check X2 = Value of part 1 leakage check on Flowmeter
parts 1 and 2 (X2< 4.0 ml/min)
X3 = Value of part 2 leakage check on Flowmeter
(X3< 4.0 ml/min)
Pump Check X4 = difference in pressure between cell pressure and
ambient pressure displayed on the M3046A during occlu-
sion (X4 >120 mmHg)
Flow Check X5 = difference between measured value and 50.0 ml/min
(X5<7.5 ml/min)
Noise Check X6 = Noise Index displayed on M3046A (X6<3.0)
