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.
