Hioki clamp 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
