Amprobe MO-100 Milliohm Meter Digital milliohm meter measures resistance up to 2,000 ohms Four input terminals for taking four-wire resistance measurements, which are more accurate than two-wire resistance measurements 100 microohm resolution for measuring small amounts of resistance Choice of three test currents for more precise readings Over-temperature and over-voltage warnings help prevent damage to the meter Accurate four terminal measurement down to 100 ohms does not require test leads resistance compensation Ranges from 200.0m ohms to 2000 ohms with minimum resolution of 100 Ohm O-Ring sealed enclosure Indicates measurement errors due to temperature or connection problems Battery powered ,IEC / EN 61010-1 ,Test leads, Instruction manual, Shoulder belt, 1.5V(AA) x 8 Batteries
