8. To begin the overpressure test, press the Test button, then increase the pressure
to the overpressure point:
• Increase pressure to approximately 280mmHg using the hand bulb.
• Very slowly increase the pressure as you approach the overpressure point.
• When the overpressure point is reached, the valves will open (a faint click
can be heard when this occurs) and the pressure will rapidly reduce to 0
(zero) mmHg. Be sure to observe the pressure measurement on the
manometer when the valves open.
9. Determine if the NIBP module passed the overpressure test:
• If the valves opened WITHIN the overpressure pass criteria, then the NIBP
module PASSED the overpressure test for adults and pediatrics. Go to step
10.
• If the valves opened BEYOND the overpressure point pass criteria, then press
the Test button again to confirm the overpressure point. If the valves open
repetitively beyond the pass criteria, contact Masimo Technical Services. See
Masimo Technical Services on page 160.
10. To stop testing, press Stop.
11. Disconnect the manometer, 500mL bottle or cuff wrapped around solid object,
and hand bulb from the NIBP module.
12. Power OFF the manometer.
