20A/200A AC/DC Clamp Meters with Analog Output and Peak Hold for Inrush Measurement Applications
Hioki clamp on meters are best-in-class measuring devices incorporating Hioki’s expertise in current sensing technology. The 3284 is an AC/DC current and voltage clamp meter with analog output capabilities and a peak hold function.
• Analog output for current measuring level, current measuring waveform, or frequency measuring level.
• Peak hold function displays the crest value of the inrush current occurring when electrical equipment starts
• AC+DC mode enables measurement of the RMS value of full- or half-wave rectified waveforms
