NIBP Accuracy Test

Tool required:

 T-shape connector

 Appropriate tubing



Manometer bulb

 Rigid Vessel with volume 500 ± 25 ml

 Reference manometer (calibrated with accuracy equal to or better than 0.75

mmHg)

Follow this procedure to perform the accuracy test:

1. Connect the equipment as shown below.

2. Before inflation, check that the reading of the manometer is 0. If not, turn off the

manometer bulb to let the whole airway open to the atmosphere. Turn on the

manometer bulb after the reading is 0.

3. Select [Main]→[Maintenance >>]→[User Settings>>]→Enter required

password→[

Module Maintenance >>]→[NIBP Accuracy Test].

4. Check the manometer values and the monitor values. Both should be 0 mmHg.

5. Raise the pressure in the rigid vessel to 50 mmHg with the manometer bulb. Then,

wait for 10 seconds to let the measured values become stable.

6. Compare the manometer values with the monitor values. The difference between

the manometer and displayed values should be ± 3 mmHg. If it is greater than ± 3

mmHg, contact Mindray Technical Support.

7. Raise the pressure in the rigid vessel to 200 mmHg with the manometer bulb.

Then, wait for 10 seconds to let the measured values become stable. Repeat step

NOTE

 You can use an NIBP simulator to replace the manometer bulb and the

reference manometer to perform the test.
