4. Press the VENT soft key to release any unwanted pressure in the system
before performing the test. This feature vents the system for approximately
five seconds and can be repeated as needed to return pressure to zero.
5. Press the <START> soft key to make the Tester deliver air to the system.
Once the system under test reaches the target pressure, the test begins. The
pressure leak rate of the system and the current system pressure are shown
during the test. The leak rate is expressed in mmHg/min by default or can
appear in kPa/min, cmH
2
O/min, inH
2
O/min, or psi/min, depending on the
pressure measurement unit selection. The leak rate of the Tester is < 2
mmHg/minute.
Note
When testing with an NIBP monitor in the system, it is necessary to put
the monitor in “Service” mode, because most monitors leave the system
open to the atmosphere.
6. Press HOME to return to the Main menu.
Pressure Relief Test
The Pressure Relief Test increases the pressure in the pneumatic system until the
relief valve on the NIBP monitor opens, or until the Setpoint is reached, whichever
occurs first.
