Tolerances are based on the preset matching parameters. Higher tolerances are to be expected for calculated
values dependent on the matching factors for currents and voltages.

Tolerances are based on the preset matching parameters for a protected object with 2 sides and 1 measuring
location on each side. Higher tolerances are to be expected for calculated values dependent on the matching
factors for currents and the number of measuring locations.
