Product Overview: Clamp meters, also called clamp-on meters, are typically used to measure properties of electrical current without physically touching or disconnecting the conductor. This digital clamp meter is an auto-ranging multimeter that has two jaws which can close around an electrical conductor up to 26mm in diameter to measure AC/DC current up to 400 amp without interrupting the circuit. It is enabled with new feature for measuring a true RMS value of alternating signals (TRMS) which older models can not. That's why if exact measurement matters to us, it's more certain to measure by a device equipped by a TRMS measurement. WARRANTY: This product has one year warranty.
