Configuration examples:
Example 1:
A 2t crane scale should be configured from 0 kg to 2000 kg on the 4-20 mA interface. 0 kg
corresponds to 4 mA, 1550, 5 kg corresponds to 20 mA.
Example 2:
A 30 t scale is to be configured to empty, 0 kg equals 20 mA, -30000 kg equals 4 mA.
Example 3:
A 5 t scale is to be configured from -5000 kg to +5000 kg. In addition, it is to be switched off
in the event of an overload. -5000 kg corresponds to 4 mA, +5000 kg corresponds to 20 mA.
