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 button is pressed, or

• can be read/written via the RS232C interface.

If the pressure is lower than the setpoint, the corresponding LED
( or ) is lit solid and the corresponding relay
(

 19) is energized.
