AEMC Instruments 2129.83 - 6292 Micro-Ohmmeter - 200A/1 Ohm

The AEMC Instruments Model 6292 high-current Micro-ohmmeter is a portable, microprocessor-controlled instrument. It incorporates optimized filters and protection for measurements in electrical substations. The Model 6292 can be used to accurately measure very low contact resistances on high voltage circuit-breakers and switches, busbars, etc., with test currents up to 200A. It employs the 4 terminal-method Kelvin principle to eliminate errors caused by test leads and their contact resistances.

Measurement accuracy is assured 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 of resistances up to 1 Ohm with resolution as low as 0.1µOhm. Test currents may be adjusted by the operator and are displayed on the digital display.
