AEMC 6240 Micro-Ohmmeter

    The 10A Micro-Ohmmeter Model 6240 is a rugged, low resistance tester designed for both plant maintenance and field use. Utilizing a four-lead Kelvin method of testing, the Model 6240 Micro-Ohmmeter accurately measures very low resistance within 0.25%. Resistance measurements are automatically calculated from 1 µÎ© to 400Ω with resolutions down to 1 µÎ©. The Model 6240 has selectable test currents of 10A, 1A, 100mA and 10mA and includes a polarity reversal function. The Model 6240 is designed to conduct tests on both resistive and inductive material. Up to 99 measurements can be stored and printed directly to a printer or from a PC.

    The front end of the micro-ohmmeter employs a four-wire Kelvin configuration, which eliminates test lead resistance for a measurement accuracy of 0.25%. A built-in circuit filters out AC signals. The Micro-ohmmeter Model 6240 is packaged in a sealed field case well suited for shop and field use. Power is supplied by a long-life NiMH battery pack with a built-in recharger (110/220V). The large, easy-to-read liquid crystal display is 2.25 x 4.00". It displays the value of resistance, cur or voltage test, polarity and battery charge. For operator safety and instrument protection, the micro-ohmmeter is fuse protected at the inputs. One fuse, accessible from the front panel, protects against stored energy in inductive loads.
