AEMC 6290 Portable Digital Micro-Ohmmeter

The AEMC high-current Micro-Ohmmeter Model 6290 is a portable, microprocessor controlled instrument. It has optimized filters and protection for measurements in electrical substation. The 6290 can be used to accurately measure very low contact resistances on 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.
 

It has internal memory for storing up to 200 readings. The USB interface 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 and size. The case is made of hard plastic, highly resistant to impact and environmental conditions. Internal, thermal sensors, in all sensitive components, prevent damage to the instrument caused by overheating.
