Basic Pneumatic
Leakage Test (NBP
test) After 1 minute at approximately
250 mmHg, pressure drops no
more than 6 mmHg. BPL: Px6

3. In the case of the NiBP Deflation Rate Test, applicable to the A3 only.
NiBP Leakage Test After 1 Minute at 250 mmHg,
pressure drops no more than
6 mmHg Record Pressure
Drop in mmHg = X2
NiBP Inflation Rate
Test Monitor Reports NiBP = 280
mmHg in <6 seconds Record Time to
280 mmHg in
Seconds = X3
NiBP Overpressure
Test Overpressure Deflation is
activated at a value between
280 mmHg to 330 mmHg Record value in
mmHg at which
Overpressure
Deflation occurs =X4
NiBP Deflation Rate
Test (A3 only) Monitor reports NiBP >10
mmHg and <190 mmHg Record value in
mmHg on monitor at
1 min = X5
