Micro-Ohmmeter offers selectable test currents from 5-200 A.
Press Release Summary:
Powered from 120 V or 230 V, 50/60 Hz, Model 6292 employs 4-terminal Kelvin method to measure contact resistance from 0.1 嵽 to 1 Ω on high voltage circuit breakers, switches, and busbars. Portable instrument offers resolution as low as 0.1 μΩ. Suitable for laboratory and field use, water-resistant meter includes backlit alphanumeric LCD with up to 4.5-digit resolution, internal memory for storing up to 8,000 readings, and USB interface for connecting to computer to download stored values.
Original Press Release:
AEMC® Introduces the NEW 200 Amp Micro-Ohmmeter Model 6292
The AEMC® high current Micro-Ohmmeter Model 6292 measures very low contact resistances on high voltage circuit breakers, switches, busbars, and other locations with user-selectable test currents from 5 to 200A. The Model 6292 is powered from 120V or 230V, 50/60Hz. This portable instrument incorporates optimized filters and protection for measurements in electrical substations. It employs the four-terminal Kelvin method to prevent errors caused by test leads and their contact resistances.
To guarantee measurement accuracy, the Model 6292 features a state-of-the-art signal amplification system, offset-free with high long-term stability. A backlit alphanumeric LCD display shows resistance readings with up to 4.5 digit resolution. The instrument allows measurement resistances up to 1Ω with resolution as low as 0.1μΩ. Test currents can be user-adjusted and shown on the display. The instrument includes an internal memory for storing up to 8000 readings, and a USB interface for connecting to a computer to download the stored values.
The Model 6292 incorporates an advanced highcurrent generation system using the smaller components that significantly decreases its size and weight (24 lbs/11 kg), resulting in a rugged but lightweight instrument that can easily be carried by one person. The hard plastic case is highly resistant to impact and environmental conditions. Internal thermal sensors in all sensitive components protect the instrument from overheating.
The Model 6292 is water-resistant and can be used in poor weather conditions (IP54 with closed lid), providing excellent service both in the laboratory and in the field.
