4.3 Switching Functions

The two switching functions can be adjusted to any pressure

within the whole measurement range (→  13).

The current setpoint setting

• is output at the D-Sub connector instead of the measurement

signal (→  18) 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

is lit (<1> or <2>) and the corresponding relay (→  18) is

energized.
