The AEMC high-current Micro-Ohmmeter Model 6290 is a portable, microprocessor-controlled instrument. It has optimized filters and protection for measurements in electrical substations. The Model 6290 can be used to accurately measure very low contact resistances of high voltage circuit breakers, switches, busbars, etc., with test currents up to 200A. It employs the four-terminal Kelvin method to prevent errors caused by test leads and their contact resistances
Features
Accurately measures low contact resistances with test currents up to 200A
Analog bargraph indicator with backlit digital display
