Scaling means converting the measured value into a certain param-
eter and unit. The indication can then show the volume in litres e.g.,
instead of the percentage value. Indication values from -9999 to
+9999 are possible.
1. First of all, determine the max. indicating range and the number of
decimal places after the decimal point -- max. four decimal places
