1. A measurement input for connecting a small signal transformer to an electrical device, the measurement input comprising:
an electrical input for connecting a connection line of the small signal transformer;
an electrical output for outputting a measurement signal to the electrical device; and
a correction element having a digital filter with a filter transfer function adapted to the small signal transformer;
the filter transfer function of the correction element being defined by a parameter set, the parameter set configured to be variably preset specifically for the small signal transformer, and the parameter set configured to be preset specifically for different types of small signal transformers for current measurement and for voltage measurement.
