6240 Micro-Ohmmeters

Specifications(PDF)

The 10AMicro-Ohmmeter Model 6240 is a rugged, low resistance tester designed for bothplant maintenance and field use.
Utilizing a four-lead Kelvin method of testing, the Model 6240 Micro-Ohmmeteraccurately measures very low resistance within 0.25%.

Resistance measurements are automaticallycalculated from 1µΩ to 400Ω with resolutions down to 1µΩ.
The Model 6240 has selectable test currents of 10A, 1A, 100mA and 10mA andincludes a polarity reversal function.

The Model 6240 is designed to conduct tests onboth resistive and inductive material.
Up to 99 measurements can be stored and printed directly to a printer or from aPC.

The DataView^® Software includedallows you to configure the instrument, temperature compensate the test results,
as well as, store data and print reports.
