The AEMC high-current
Micro-Ohmmeter, AEMC 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 and switches, busbars, etc., with test currents up to 200A. It employs the four terminal-method Kelvin principle to avoid errors caused by test leads and their contact resistances.
Measurement accuracy is guaranteed through a state-of-the-art signal amplification system, offset-free with high long-term stability. Resistance readings are shown in the alphanumeric display with up to 4.5 digit resolution. It allows measurement resistances up to 20mΩ, and resolution of 0.1μΩ.
