Diagnostic Mode

Configuring the Power-up Defaults Menu  

When in the NBP Test screen, the Return option is always highlighted. Press the wheel to 
return to the Diagnostic Menu. Rotating the wheel while in the NBP Test screen has no 
effect.

Activate Pump

As long as the NBP button is pressed, 
the pump runs. If system pressure 
reaches the hardware over-pressure 
protection point (280 to 330 mmHg or 
37.3 to 44.0 kPa), the safety valve opens 
and the pump disables, until the pressure 
falls below the safety threshold.

Open Both Valves

As long as the Volume button is pressed, 
the safety valve and proportional valve 
opens and remains at maximum. 

Deflate

As long as the Alarm Silence button is 
pressed, the proportional valve opens 
and bleeds off pressure at the rate of 3 

±

1.5 mmHg/s. It is useful to control the 

bleed rate to 3mmHg/s to facilitate 
certain AAMI SP10 tests. Any time the 
bleed rate falls below 3 mmHg/s, the 
valve opens and remains at maximum as 
long as the button is pressed.

Offset Adjustment

Momentarily press the Contrast Adjust 
button invokes the Zero Calibration 
routine that is performed immediately 
prior to each blood pressure 
measurement. This routine looks at the 
pressure in the system, and if the 
pressure is non-zero, an offset is applied 
which causes the system pressure to 
display as Zero.
