Micro-Ohmmeter Model 6240

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 5 µΩ to 400 Ω with resolutions down to 1 µΩ. The Model 6240 has selectable test currents of 10 A, 1 A, 100 mA and 10 mA 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.

DataView ® (included) allows you to configure the instrument, temperature-compensate the test results, store data, and print reports.
