The 10A microhmmeter 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 microhmmeter accurately measures very low resistance within 0.25%. Resistance measurements are automatically calculated from 1 microhm - 400 ohm with resolutions down to 1 microhm. 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.
