Key Features • Wireless support. Transfers measurements to your smartphone or tablet. (Optional Wireless Adapter Z3210 is necessary) • Detect minuscule leakage currents with a newly designed sensor. (Core jaw diameter up to φ 40 mm) • Broad measurement range extending from leakage currents to load currents • Complies with the performance standard set forth in IEC/EN 61557-13, an international standard on leak clamp meters • Solve GFCI and RCD problems quickly • Speed up pass/fail judgments with the built-in comparator function • Output function (waveform/RMS): use with a recorder to record waveforms and fluctuations • External power supply: use an optional AC adapter for continuous, long-term measurement CAT III 300 V
