The 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. The Model 6292 is powered from 120V or 230V, 50/60Hz. This portable instrument incorporates optimized filters and protection for measurements in electrical substations. It employs the four-terminal Kelvin method to prevent errors caused by test leads and their contact resistances.
Model 6292 features a state-of-the-art signal amplification system, offset-free with high long-term stability. A backlit alphanumeric LCD display shows resistance readings with up to 4.5 digit resolution. The instrument allows measurement resistances up to 1Ω with resolution as low as 0.1μΩ. Test currents can be user-adjusted and shown on the display. The instrument includes an internal memory for storing up to 8000 readings, and a USB interface for connecting to a computer to download the stored values.
