S10 is a mini Rogowski coil integrator combine with power meter or PLC, in a plastic enclosure, powered directly from the mains. An integrator amplifies the weak voltage signal from the Rogowski coil into standard signal to be used by multimeter and scope. Rogowski coil output is proportional to the frequency of the measured current, the signal equalization ensure a linear response on a wide frequency range. S10 allows to use coils on different electrical network frequencies, keeping the same output level over the frequencies.
