DANGER
DANGER: malfunction
If processes are controlled via the signal output,
keep in mind that by pushing the button the
measurement signal is suppressed and the cor-
responding threshold value is output instead. This
can cause malfunctions.
Push the button only if you are sure that no
damages can arise from a malfunction.
Adjusting Setpoint <1>

Push the button with a pin (max. ø1.1 mm). The
gauge changes to the switching function mode and outputs
the current threshold value at the measurement value
output for about 10 s (LED <1> blinks).
