The Agilent/Keysight U1191A is a handheld clamp meter designed for AC current measurements. It features a 6,000-count resolution display and an average-responding AC current measurement capability up to 400 A. This instrument is equipped with a unique wire separator to assist in isolating individual wires within a bundle for measurement. It also offers integrated DMM functions including resistance, AC voltage, and DC voltage measurements. For safety, the U1191A is protected by CAT III 600 V and CAT IV 300 V overvoltage ratings.
