AEMC WCM-AEMC-6292 AEMC 6292 Micro-Ohmmeter

This high-current Micro-Ohmmeter is a portable, microprocessor-controlled instrument. It has optimized filters and protection for measurements in electrical substations. The AEMC-6292 can be used to accurately measure very low contact resistances of high voltage circuit breakers, switches, busbars, etc., with test currents up to 200A.

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 4½-digit resolution. It allows measurement resistances up to 1Ω, and resolution of 0.1µΩ.
