crest value
OUTPUT CORD
9094
The peak hold function displays
the crest value of the inrush
current occurring when electrical
equipment is started.
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

The AC+DC mode enables
measurement of the RMS value
of full- or half-wave rectified
waveforms used in electrical
machinery.
