Description
Model: AEMC Model 6255 Micro-Ohmmeter
Part Number: 2129.84
Order Number: 1D0331
The 10A Micro-Ohmmeter Model 6255 is a rugged, low resistance tester designed for both plant maintenance and field use. Utilizing a four-lead Kelvin method, the Model 6255 is the most accurate Micro-Ohmmeter available, with results within 0.05%. It can test up to 60 minutes continuously at 10A.
The Model 6255 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; resistive (instantaneous test), inductive (continuous test), and auto (repetitive test). Up to 1500 measurements can be stored and printed directly to a printer from a PC.
The DataView® Software included allows you to configure the instrument, store data and print reports.
