EX650: 600A True RMS AC Clamp Meter + NCV

Choice of AC Current (EX650) or fully loaded advanced
AC/DC Current (EX655) model. Both meters feature
True RMS providing accurate readings when measuring
distorted or noisy waveforms and Low Impedance
(LoZ) mode to eliminate false readings caused by ghost
voltages. EX655 also features Low pass filter (LPF)
which attenuates high frequencies to reduce noise for
accurate readings and Inrush mode to capture current
surges during motor startup
