In the following there are the measuring ranges with function-number listed,
which were supported by the analog module.
With FFh the corresponding channel is deactivated.
The formulas listed here allow you to transform an evaluated measuring
value (digital value) to a value assigned to the measuring range (analog
value) and vice versa.
