You may also perform a manual leakage test:
1. Perform steps 1 to 4 in the NIBP Accuracy Test section.
2. Raise the pressure in the rigid vessel to 250 mmHg with the manometer bulb.
Then, wait for 5 seconds to allow the pressure to stabilize.
3. Record the current pressure value, wait 60 seconds and record the pressure again.
4. Compare the two pressure values and verify the difference is 6mmHg or less.
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.
