Procedure
1. Enter NIBP menu, select "Calibration".
2. Enter password: 4258 and touch "Calibration Test".
3. Connect a manometer, volume and the hand bulb to the Module using "T" adapters
and connection tubing.
4. Touch the "Test" button on the display to start the calibration.
5. Apply various pressures (between 0 mmHg and 280 mmHg) to the Module with
the hand bulb. Verify that the Module pressure is equal to the manometer pressure
(±3mmHg). If the Module pressure does not agree with the manometer pressure
(±3mmHg), perform the Zero Point Calibration and the Span Point Calibration.
Then perform this calibration again.
6. Calibration is now complete.

Pass Criteria
International standards for automated NIBP devices require that air leakage within the
pneumatic system must not exceed 6mmHg/minute.
Procedure
1. Connect the manometer and rigid volume (500 mL bottle) to the air hose
connection using "T" adapters and connection tubing.
2. Enter NIBP menu, select "Calibration".
3. Enter password: 4258 and select "Air Leak Test".
4. Touch the "Test" button on the display to start the test.
5. Wait for the countdown timer to reach 0 second.
6. Check the "Result" section, if the leak rate is greater than 6 mmHg/min, contact
customer service.
Zero Point Calibration

only.
Calibration Steps
1. Enter NIBP menu, select "Calibration".
2. Enter password: 4258 and select "Zero Point Calibration".
3. Connect a manometer, volume and the hand bulb to the Module using "T" adapters
and connection tubing.
4. Apply 0 (zero) mmHg to the module.
5. Touch the "Calibrate" to start the zero point calibration.
6. Results are displayed for Zero Point Calibration.
