Hioki clamp meters are best in class handheld current and voltage meters for safely and accurately measuring power lines. The 3286-20 can measure voltage, current, power, power factor, phase angle, reactive power or frequency, as well as detect phase sequence on live lines at any desired point of a single-phase circuit or three-phase circuit.
OVERVIEW
• Measure single-phase 600 kW lines and up to the 20th harmonic level
• Active/ reactive/ apparent power, power factor, phase detection, frequency, harmonic waveform value, or waveform peak value
• Simple checking of three-phase lines (balanced with no distortion)
Specifications
■ Basic specifications (Accuracy guaranteed for 1 year, or opening and closing of the clamp sensor 10,000 times)
