Using the external output functions of the 3284 or 3285 in combination with a HIOKI MEMORY HiCORDER enables recording of current and frequency fluctuations and recording and harmonic analysis of instantaneous waveforms. The monitor output (MON) spans a wide frequency range from DC to 20 kHz (15 kHz in the case of 3285), which allows the units to be used for electric current analysis in various fields ranging from batteries to inverters. Example of analysis using the MEMORY HiCORDER
current waveform
(inverter output )
The AC+DC mode enables measurement of the RMS value of full- or half-wave rectified waveforms used in electrical machinery.
