The Extech EX655 clamp meter performs 12 core functions including True RMS AC/DC current measurement. It features a Low Pass Filter (LPF) which attenuates high frequencies to reduce noise for accurate readings of variable frequency drive (VFD) signals, and an Inrush mode to capture transient current surges during motor startup. True RMS technology provides accurate readings when measuring distorted or noisy waveforms, and Low Impedance (LoZ) mode eliminates false readings caused by ghost voltages in electrical systems.
