NIBP Module Calibration Test
Note: This section is provided as a reference and intended for authorized
service personnel 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.
Equipment
 Calibrated Manometer*
 Pneumatic "T" Adapters
 500mL bottle or regular-sized cuff wrapped around solid object
 Hand Bulb
