1mA to 200A AC Leakage Current Clamp Meter with 10 µA Resolution to Analyze Distorted Waveforms



Hioki clamp on meters are best-in-class measuring devices incorporating Hioki’s expertise in current sensing technology CLAMP ON LEAK HiTESTER

The Hioki 3283 series are leakage current handheld clamp meters with a 10mA to 200A range and 10 μA resolution. Model 3283 has output capabilities for advanced monitoring on recording equipment, and Model 3283-20 complies with EN 61010-2-032:2012 Type A standards to measure uninsulated hazardous live conductors such as busbars.

Order Code

3283 Not CE marked, with analog / waveform monitor output
3283-20 CE marked, without analog / waveform monitor output
CE3283 TrueRMSDC3283-20 only
Insulated conductor

Key Features

• Measure leak current using highly sensitive 10μA resolution (at 10.00 mA range)

• Indicate 50/60 Hz leak current components with the filtering function

• Monitor leak current conditions in combination with a Memory HiCorder (monitor output, Model 3283 only)

• 3283-20: EN 61010-2-032:2012 Type A to measure uninsulated hazardous live conductors such as busbars

■ Basic specifications (Accuracy guaranteed for 1 year, Post-adjustment accuracy guaranteed for 1 year)
