NEPTUNE - Insulation and Continuity professional multimeter

Continuity of protective conductors with 200mA. I check the continuity of protective and equipotential conductors (PE) with a test current of 200mA. I carry out tests between earth poles of all plug sockets and on the earth node. I check continuity of the main external masses like water or gas pipes and earth node.

I measure voltage accurately. I measure AC/DC voltage with a “low impedance input” (LoZ) in order to eliminate incorrect readings due to stray voltages because of parasitic capacitive coupling.

Harmonics. An open book to me. I measure THD% and values of voltage and current harmonics, expressed both in absolute and in percentage value I have H20 function (Higher Harmonic Ordering), which orders harmonics by amplitude, immediately displaying the values of the highest harmonics found in the system with no need to “scroll down” all harmonics in order to identify the highest values

Current measurement. I measure AC/DC current through the external clamp transducer of type “Standard” or “Flexible” up to 3000A I can also measure leakage current starting from 1mA through the optional clamp transducer HT96U I measure inrush currents of electric motors and loads through DIRC function which allows measuring inrush currents with user-defined time frames. I use function AC+DC to detect a possible presence of overlapping direct components on a generic alternating current.
