With a full range of AC current, AC/DC voltage and frequency measurement functions for basic electrical troubleshooting, this clamp meter with its large backlit display is an excellent amp clamp meter choice. Rated CAT III 600 V, this clamp meter offers True-RMS sensing, fast response processor, non-contact voltage detection, capacitance, resistance and continuity measurements to enhance efficiency and safety in today's complex electrical environments. The amp-tip function allows for precise measurement of current down to the tenth of an amp, enabling accurate current measurement of both large and small diameter wires. A low pass filter allows measurement of current and voltage on variable frequency drives (motors with speed controlled by frequency).
