The AEMC 6255 10 A micro-ohmmeter is a rugged, low resistance tester designed for plant maintenance, quality control in manufacturing, and field use. Utilizing a four-lead Kelvin method of testing, the 6255 is one of the most accurate micro-ohmmmeters available with results up to 0.05% accuracy.

Resistance measurements are automatically calculated and displayed taking into account the measurement value, ambient temperature, reference temperature, and metal temperature coefficient. Sample temperature can be manually entered by the operator or directly measured by the AEMC 6255 with an external RDT temperature probe.

The AEMC 6255 micro-ohmmeter is uniquely designed to conduct tests on both resistive and inductive material with operator selection directly from the front panel. Three test modes are available and automatically employed based on this selection: Resistive (instantaneous test), Inductive (continuous test), Auto test mode (multiple test points on resistive and/or low inductance material).

Applications: Aerospace metallic coating resistance measurement, Winding resistance measurement of motors and transformers, 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, Mechanical bond tests.
