Why the coils are sold as a kit with the multimeter?

The output signal of a Rogowski coil must be processed in order to amplify, shift and filter it. Those operations are in charge of DMG611R… multimeter. The level of signal processing depends on each single coil piece, thus it is necessary that each measuring current input of DMG611R… is coupled and calibrated to get the [...]

When is a measurement solution with Rogowski coils current inputs convenient?

Two fundamental differences arise between a traditional split-core current transformer and a Rogowski coil, even if both of them are current transducers: the Rogowski coil is flexible and deformable, while a CT is rigid and non-deformable;  considering the same primary current, the Rogowski coil occupies less space. For those reasons, the solution with Rogowski coils [...]

How does the minimum measurement current indicated for the measuring device influence the energy data?

The accuracy of the measuring instruments is guaranteed within a range of current values indicated by the manufacturer. In particular, below the minimum value the instrument is no longer required to measure with the prescribed accuracy. It is therefore necessary to pay attention to situations in which the current absorbed by the loads varies frequently [...]
