The high-current Micro-ohmmeter Model 6292 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 1Ω with resolution as low as 0.1µΩ. Test currents may be adjusted by the operator and are displayed on the digital display.
