200 Amp Micro-ohmmeter measures low contact resistances

AEMC high current Micro-Ohmmeter Model 6292 measures very low contact resistances on high voltage circuit breakers, switches, busbars and other locations with user-selectable test currents from 5 to 200A. Portable unit is powered from 120V or 230V, 50/60Hz, incorporating optimized filters and protection for measurements in electrical substations. Product employs the four-terminal Kelvin method to prevent errors caused by test leads and their contact resistances. Unit provides a state-of-the-art signal amplification system, offset-free with high long-term stability.
