3.3.2.1 Set-point
The set-point output is an open-collector transistor with a series diode. When the pressure falls to the set-point
value, the transistor output changes to on (closed or low impedance) and the set-point LED switches on (amber). The
set-point has a fixed hysteresis of 500 mV: the set-point output and LED go off when the pressure rises to 500 mV
above the set-point pressure.
