9. Apply various pressures (0mmHg to 280mmHg) to the NIBP module with the
hand bulb.
10. Compare the NIBP module pressure to the manometer pressure:
• If the NIBP module pressure and manometer pressure differ WITHIN the
±3mmHg tolerance, then the NIBP module has PASSED the calibration test
and no further action is needed. Go to step 11.
• If the NIBP module pressure and manometer pressure differ BEYOND the
±3mmHg tolerance, (1) perform the Zero Point Calibration, (2) then perform
the Span Point Calibration. See Zero Point Calibration on page 152 and Span
Point Calibration on page 153. If the NIBP module pressure and manometer
pressure still differ BEYOND the ±3mmHg tolerance, contact Masimo
Technical Services. See Masimo Technical Services on page 160.
11. Disconnect the manometer, 500mL bottle or cuff wrapped around solid object,
and hand bulb from the NIBP module.
12. Power OFF the manometer.
Zero Point Calibration
Zero Point Calibration is performed when an NIBP module does NOT PASS the NIBP Module
Calibration Test. See the NIBP Module Calibration Test on page 150.
Note: This section is provided as a reference and intended for authorized service personnel
only.
1. Press the back button in the upper-left corner of the CALIBRATION TEST screen to
go back to the CALIBRATION menu screen.
2. Select ZERO POINT CALIBRATION .
3. Apply 0 (zero) mmHg to the NIBP module.
Note: The 0 (zero) mmHg can be verified on the manometer.
4. Press Calibrate to start the Zero Point Calibration:
• A "Success" message will appear if the calibration was successful. Go to step
5.
• If a "Result Failure" message appears, verify the 0 (zero) mmHg is applied to
the NIBP module and press Calibrate again. If the "Result Failure" message is
repetitive, contact Masimo Technical Services. See Masimo Technical
Services on page 160.
5. After a successful Zero Point Calibration, complete the Span Point Calibration. See
Span Point Calibration on page 153.
