If a higher beam number is selected for the beginning of the measurement range than for the end of the
measurement range, the characteristic curve is inverted.

Overview: states of the analog output
The rise time of the analog output from 0% to 100% can take up to 2 ms. To keep the control from evalua
-
ting the analog value of a rising edge, configure the control so that a value is detected as valid if it remains
unchanged for a certain length of time.
