NIBP Module Calibration
Note:
This section is provided as a reference and intended for qualified service professionals
only.
Pass Criteria
International standards for automated NIBP devices require that the maximum static
pressure accuracy shall be ± 3mmHg or 2% or the reading, whichever is greater. This is a
stringent requirement and all test equipment must be in excellent working order to properly
perform this test. It is important to verify the calibration before changing it. Historical data
has shown that the transducers rarely need to be re-calibrated although we still suggest that
the calibration be verified annually.
Procedure
1.
Enter NIBP menu, select "Calibration".
2.
Connect a manometer, volume and the hand bulb to the Module using "T" adapters
and connection tubing.
3.
Touch the "Test" button on the display to start the calibration.
4.
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.
5.
Calibration is now complete.
