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
6.
NOTE
 You can use an NIBP simulator to replace the manometer bulb and the
reference manometer to perform the test.
NIBP
Cuff Overpressure Test
Tools required:
 T-shape connector
 Appropriate tubing

Manometer bulb
 Metal 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 calibration:
1. Perform steps 1 to 4 in the NIBP Accuracy Test section.
2. Select [
Main]→[Maintenance >>]→[Factory Maintenance >>]→enter the required
password→[
Calibrate NIBP >>]→[Overpressure Protection Circuit].
3. In [
Overpressure Protection Circuit] menu, set [Patient Category] to [Adu/Ped].
Raise the pressure to 330 mmHg. After the pressure value is stabilized, select
[Calibrate] to start calibration.
4. In the [Overpressure Protection Circuit] menu, set [Patient Category] to
[
Neonatal]. Raise the pressure to 165 mmHg. When the pressure value is stabilized,
select [
Calibrate] to start calibration.
5. All calibration results are displayed in the [Calibrate NIBP] menu. If the calibration
fails, check the test system for leakage and perform another calibration.
