to NIBP SEAL <-- OFF .

the technician to manual test the pressure transducer with a
manometer.
Pump up the manual squeeze bulb. Verify that the manometer
readings agree with the monitor readings. The accuracy of the
pressure transducer for static pressure measurements should be
within ±2 mmHg or ±2% of reading, whichever is greater. The current
pressure will be displayed in the LCD window.
