The AEMC 6240 10A micro-ohmmeter is a rugged, low resistance tester designed for both plant and field use. It is a cost effective, feature rich instrument designed for measuring contact resistance, bond resistance and other low resistance connections. The 6240 accurately measures very low resistance with 0.25% accuracy utilizing a four-lead Kelvin method of testing.

An internal NiMH battery pack is rechargeable from 110/230V, 50/60Hz. A fully charged battery can perform up to 850, 10A tests. Resistance measurements are automatically calculated from 1µΩ to 400Ω with resolutions down to 1µΩ.

The AEMC 6240 Micro-Ohmmeter has selectable test currents of 10A, 1A, 100mA and 10mA and includes a polarity reversal function. The 6240 is designed to conduct tests on both resistive and inductive material. Polarity reversal is easily accomplished with a push of a button. The resistance measurements of both positive and negative test results, as well as the average, are displayed. The included DataView software allows you to download data, temperature compensate the test results, store data, and print reports using predefined or custom templates.

Applications include aerospace metallic coating resistance measurement, bonding verification on earth/ground systems, weld joint integrity verification, contact resistance measurement of breakers and switchgear, aircraft and rail bonding checks, wire to terminal connections and resistance checks, battery strap resistance checks, cable joint and bus bar connection checks, and mechanical bond tests.
