200A/2000A AC/DC Clamp Meters with Continuity Check and Resistance Testing or Analog Output
Hioki clamp on meters are best-in-class measuring devices incorporating Hioki’s expertise in current sensing technology. The 3285 and 3285-10 measure DC, AC or AC+DC current in live power lines without tapping into or connecting the lines, and includes a variety of features and functions including automatic zero adjustment that turns a normally troublesome task into a one-touch operation. Model 3285 comes with AC adapter and output terminals to enable connection to other instruments such as recorders.
• Analog output for current measuring level, current measuring waveform, or frequency measuring level.
• Peak hold function displays the crest value peak current up to 2840 A
• AC+DC mode enables measurement of the RMS value of full- or half-wave rectified waveforms
• Model 3285-20 adds resistance and continuity check functions
■ Basic specifications (Accuracy guaranteed for 1 year, or opening and closing of the clamp sensor 10,000 times)
