This professional multimeter features true RMS measurements for accurate readings of noisy, distorted, or non-sinusoidal waveforms. It includes a Smart Auto Sense function that automatically detects the input mode, a built-in non-contact voltage detector (NCV), and a low pass filter (LPF) for precise measurement of variable frequency drive signals. The device also offers inrush current measurement, a 6000-count backlit LCD display, and Smart Data Hold with an audiovisual alert for readings exceeding 50 digits. Additional features include a low battery indicator, auto power-off, and a CAT III 600V safety rating. Its compact 0.8-inch (22mm) jaw size allows measurements in tight spaces. The product comes with an ISO certificate inclusive of full data and uncertainties.
