8.4 Settings - I/O Settings
Analog inputs are used to digitize signals that represent various primary values. There are a variety of
settings that can condition these input signals. These settings are briefly described below.
Parameter Description Range
Scale Scaling factor, from secondary to primary values (ratio). 0..2 000
Decimals Number of decimals for the value presented in the web interface. 0..3

Parameter Description Range
Offset Offset added to the secondary value before scaling it. 0.000..1.000
Ref value The reference value represents 100% of the nominal primary value, and
is used for the calculation of deadbands. For phase currents the
reference value is linked to the Scale value. 0..2 000
