AEMC 2129.82 - Micro-Ohmmeter Model 6290

The AEMC high-current Micro-Ohmmeter Model 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, switches, busbars, etc., with test currents up to 200A. It employs the four-terminal Kelvin method to prevent 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 4½-digit resolution. It allows measurement resistances up to 20mΩ, and a resolution of 0.1µΩ.

Applications:

• Test switchgear contact resistance
• Test circuit breaker contact resistance
• Test air frame bonding
• Test rail bonding
• Test pipeline bonding
