The 380580 is a battery-powered milliohm meter that offers five resistance ranges with a resolution as low as 0.1 milliohms. It features a 4-wire Kelvin clip connection for optimal measurement accuracy. Designed for field use, this high-precision, portable instrument includes over-temperature and overvoltage protection, invalid test indicators to prevent inaccurate readings, and a built-in water-resistant case with a shoulder strap. Suitable applications include transformer, motor coil, and PCB resistance measurements. The kit includes the milliohm meter, 8 AA batteries, and two sets of test leads—one with four alligator clips and the other with two Kelvin alligator clips.
