AEMC 6250 (2129.81) Micro-Ohmmeters

DISCONTINUED ITEM-Recommended Replacement: AEMC 6255 (2129.84) Micro-Ohmmeter, 10A

The 10A Micro-Ohmmeter Model 6250 is a low-resistance, rugged tester made for both field use and plant maintenance. Making use of a 4-lead Kelvin method, the Model 6250 is an available Micro-Ohmmeter with the utmost accuracy, with results within 0.05%.
The Model 6250 is designed uniquely to perform tests on both inductive and resistive material, with the selection of operator directly from the front panel. 3 test modes are available; auto (repetitive test), inductive (continuous test), as well as resistive (instantaneous test). Up to 1500 measurements could be stored and directly printed to a printer or from a PC.
