The pump stops when the measured pressure is the same as the target pressure. The
Product waits for a time to let the pressure to become stable. Then the Product starts
to measure and monitor the pressure for the test period.
When the test is done, the test results are shown in the display. An example pressure
test result is shown in Figure 40.

To set how long the test will run:
1. Push the Test Duration softkey.
2. Push  or  to adjust the time between 30 seconds and 5 minutes in 30 second
steps. The default time is 1 minute.
3. Push  to set the test duration and go back to the NIBP: Leak Test screen.
How to Do a Pressure Relief Test
The pressure relief test pressurizes a pneumatic system until the Product senses a drop in
pressure, as occurs when the relief valve opens. Or the test stops if the pressure gets to
the target pressure and no relief is sensed.
Note
Put the NIBP monitor in “calibrate” or “service” mode to close the vent
valve, so the Product can inflate the pneumatic system. Refer to the service
manual for the NIBP monitor.
To test the relief valve:
1. From the NIBP screen, push the Tests softkey.
2. Push  or  to highlight Pressure Relief Test.
3. Push .
4. Push  or  to increase or decrease the target pressure between 100 and 400 mmHg
in 1 mmHg steps.
Note
When you hold down the direction key, the step size will change to
10 mmHg until the key is released.
5. Push the Start softkey to begin the test.
The Product pressurizes the pneumatic system to the target pressure with the pressure
measurement and a graph of the pressure shown in the display. See Figure 39. When the
Product senses the pressure valve has opened, the test stops and the results are shown in
the display. See Figure 41. It is recommended you do three pressure relief tests in case
the relief valve is intermittent.
