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 1µΩ to 400Ω with resolutions down to 1µΩ. 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 DataView® Software included allows you to configure the instrument, temperature compensate the test results, as well as, store data and print reports.
