200Amp micro-ohmmeter measures very 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 and incorporates 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. Cooling system improves the number of sequential tests that and the duration of the test that can be performed
