The AEMC 6250 10A Micro-Ohmmeter / DLRO is a rugged, low resistance DLRO / ductor designed for plant maintenance, quality control in manufacturing and field use. Utilizing a four-lead Kelvin method of testing, the AEMC 6250 is one of the more accurate micro-ohmmeters available, with results within 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 6250 10A Micro-Ohmmeter / DLRO with an external RTD temperature probe.

The AEMC 6250 10A Micro-Ohmmeter / DLRO 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 materials (i.e. ground bonding, coatings, contact resistances) are tested with an instantaneous test. Auto test mode is designed for multiple test points on resistive and/or low inductance material.

The large, easy-to-read display shows the resistance measurement, ambient and reference temperatures, metal type and test method, as well as alarm conditions and memory utilization, all in real time. Previously stored test results can easily be called up for review on the display or sent directly to a printer or remote terminal. Two programmable alarm set points are available. Each can be either active high or low and will sound an alarm when tripped, further adding to the ease of use by permitting quick Pass/Fail measurements.
