change will be indicated. press momentarily again and the unit returns to the normal mode
of pressure differential (see fig.6).
Differential Pressure: a measurement of the difference between two pressures, i.e. use
differential pressure sensor to measure gauge pressure by leaving one process connection open
to atmosphere and connecting the second sensor port to your system.
