The AEMC 10A Micro-Ohmmeter, or Ductor Tester Model 6240 is a rugged, low resistance tester designed for both plant maintenance and field use. The 6240 ductor tester utilises a four-lead Kelvin method of testing, the Model 6240 Micro-Ohmmeter accurately measures very low resistance to within 0.25%, when performing a ductor test.

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 ductor tester 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.
