Description
The Hioki 3284 is a handheld AC/DC clamp meter that reads current up to 200 A and voltage up to 600 V. It provides true RMS, average and peak values, so it handles distorted waveforms, DC circuits and inrush current. An analog output passes current or voltage signals to a recorder or oscilloscope for waveform and harmonic work. Maintenance electricians and service engineers use it on drives, rectifiers, battery systems and general power distribution. The 3284 is an older Hioki model; check availability before ordering.
Key features
- AC, DC and AC+DC current measurement in 20 A and 200 A ranges
- True RMS, average and peak measurements for distorted waveforms
- Inrush current crest value capture
- Voltage measurement from 30 V to 600 V AC and DC
- Analog output (1 V full scale) with recorder and monitor modes
- Max, min, average recording and auto power-off
Typical applications
- Current measurement on inverters, rectifiers and variable speed drives
- Inrush current checks on motors and transformers
- DC current checks on battery and solar systems
- Feeding waveforms to an oscilloscope or recorder for harmonic analysis
