Peak value display

(6. Menu step)

- read stored peak values

A change of the output signal range or the

displayed value will return the display to null.

- erase the value with the "SET" key

max. value

min. value

Fault display during operation

Exceeding the maximum output signal voltage of approximately

(-) 13.3 V e.g. resulting from a broken sensor cable.
