Slim body design, allows easy clamping even for narrow conductors. 42A to 1000A AC Current Clamp Meters with Double Opening Jaw and Slim Profie to Get into the Narrowest Spaces Hioki clamp on meters are best-in-class measuring devices incorporating Hioki expertise in current sensing technology. The 3280-10 and 3280-20 are our most popular clamp on meters, featuring a thin and compact clamp core that lets you get into the tightest spots. True RMS vs. MEAN Value Two ways to convert alternating current to RMS are rue RMS response and verage rectified RMS response (averaging). Both display the same value for a sine wave, but can display very different values for distorted waveform High-frequency waveform components are included in the calculated RMS display value. The measured waveform is treated as a single-frequency (undistorted) sine wave,and the calculated average of the AC signal is converted to an RMS display value. Measurement error increases with waveform distortion. As inverters and switching power supplies proliferate, the need for the capability to measure distorted current waveforms grows. A true RMS clamp-on current meter is the proper tool for accurate measurements. Names and Functions of Parts Operation grip The clamp sensor at the same side as the pushed grip opens. Function switch Switching for OFF/AC current [~A] /AC voltage [~V]/DC volt- age [ V]/Resistance, Continuity check [Ω/ ] (Power is turned on in any position other than OFF & Clamp On Hi-Tester - Avg Sensing,3280-10 MEAN Value Clamp on HiTester,Measure the fundamental waveform component using the average rectified method,Wide range of max. 1
