5. Raise the pressure in the rigid vessel to 50 mmHg using the balloon pump. Then wait
for 10 seconds so that the measured values become stable.
6. Check that the difference between the reading of the manometer and that of the
monitor is less than or equal to 3 mmHg. If it is greater than 3 mmHg, contact your
service personnel.
7. Raise the pressure in the rigid vessel to 200 mmHg using the balloon pump. Then
wait for 10 seconds so that the measured values become stable. Then repeat step 6.
NOTE

You can use an NIBP simulator to replace the balloon pump and the
standard manometer.

You can use an appropriate cylinder and a cuff instead of the rigid vessel.
4.5.2.3
NIBP Overpressure Protection Test
This test mainly measures whether the NIBP overpressure protection circuit is working
properly.
Test Preparations
Test tools:

T-shape connector

Air tubing
 Balloon pump
 Rigid vessel with volume 500±25 ml

Reference manometer (calibrated with accuracy equal to or greater than 1
mmHg)
Procedure
Follow this procedure to perform the test:
1. Perform steps 1-4 in the
NIBP Accuracy Test
section.
2. Select Main Menu -> Maintenance -> enter password -> Factory Maintenance -> NIBP ->
Test .
3. In Overpressure Protection Circuit Test , select Adult/Pediatric for Patient Category ,
and adjust the pump output pressure to 320-330 mmHg. After it keeps stable, select
the Test button to start the test. When the test succeeds, the NIBP menu will display
the message of
Test Successful
. If the pressure exceeds 320-330 mmHg, the message
Test Failed will be displayed.
4. In
Overpressure Protection Circuit Test
, select
Neo
for
Patient Category
, and adjust
the pump output pressure to 160-165 mmHg. After it keeps stable, select the Test
