Set the voltage to a multiple of the threshold value. Siemens recommends setting the Threshold parameter
to 1.00 in order to obtain a simple relation. You can change the threshold value afterwards if you want to
shift the characteristic curve.
Set the time value in seconds. The characteristic curve is shifted via the Time dial parameter.
Set the number of value pairs to be used with DIGSI. You can define a maximum of 30 value pairs.
NOTE
The value pairs must be entered in continuous order.
