4.3 Switching Functions
The two switching functions can be set to any pressure within
the measurement range of the gauge (→  14).
The current setpoint setting
• is output at the D-Sub connector instead of the measurement
signal (→  19) and can be measured with a voltmeter after
the <SP> button is pressed, or
• can be read/written via the RS232C interface.
If the pressure is lower than the setpoint, the corresponding LED
(<SP1> or <SP2>) is lit solid and the corresponding relay
(→  19) is energized.
