AEMC 6290 Digital 200A Micro-Ohmmeter

The AEMC 6290 high-current Micro-ohmmeter is a portable, microprocessor-controlled instrument. The AEMC 6290 has optimized filters and protection for measurements in electrical substation. The AEMC Model 6290 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. The AEMC 6290 Digital 200A Micro-Ohmmeter employs the 4 terminal-method Kelvin principle to avoid errors caused by test leads and their contact resistances.

The AEMC 6290 200A Digital Micro-Ohmmeter has an internal memory for storing up to 200 readings. The USB interface of the AEMC 6290 may be connected to a computer to download the stored values. The high-current generation system is based on modern technology that allows for a significant decrease in both weight, 24.25 lbs (11 kg), and size. The case is made of a hard plastic, highly resistant to impact and environmental conditions. Internal, thermal sensors, in all sensitive components, prevent damage to the instrument caused by overheating.
