• At the bottom of the screen, in the Result section, verify the leak rate is less
than 6mmHg. If the leak rate is greater than 6mmHg, verify there are no
leaks in the calibration equipment (tubing, 500mL container, arm cuff, etc.).
If there are no leaks detected from the calibration equipment and the leak
rate is still greater than 6mmHg, contact Masimo Technical Services. See
Masimo Technical Services on page 160.
9. Disconnect the manometer, 500mL bottle, and hand bulb from the NIBP module.
10. Power OFF the manometer.
Overpressure 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 pressure must not
exceed 300mmHg on adults and pediatric patients and 150mmHg on neonatal patients with
a tolerance of 10% for 15 seconds or greater than 10% for 3 seconds. The overpressure pass
criteria for the Advantage module are:
Adults, Pediatrics 300 ±10mmHg
Neonates 150 ±5mmHg
Equipment
• Calibrated Manometer*
• Pneumatic "T" Adapters
• 500mL bottle or regular-sized cuff wrapped around solid object
• Hand Bulb
• Connection Tubing
*Verify the manometer has been calibrated within the last 12 months. Calibration accuracy
shall be within ±0.02% to ±0.25% FS (Full Scale) and a measurement uncertainty of ±1 LSD
(Least Significant Digit).
