February 28, 2012 – AEMC describes its new high-current micro-ohmmeter 6290 as a portable, microprocessor-controlled instrument, featuring optimized filters and protection for measurements in electrical substations. According to the company, 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, it adds.
