DescriptionChauvin Arnoux CA6255, 10A Microhmmeter c/w 2m Kelvin Clamp Cables Product Description:The Chauvin Arnoux CA6255 Precision Micro Ohmmeter is a high-accuracy instrument designed to measure low resistance with extreme precision. Ideal for electrical professionals, this micro ohmmeter offers resistance measurement capabilities ranging from 0 to 2500Ω and a maximum resolution of 0.1µΩ, ensuring highly accurate results. It features adjustable test currents from 10A to 1mA, making it adaptable to a wide variety of testing applications. The built-in memory allows storage of up to 1500 readings, which can be easily retrieved and organized under different test indices. Additionally, the CA6255 incorporates advanced temperature and stray voltage compensation through a Pt100 probe for reliable performance in varying environmental conditions. With versatile measurement modes, including non-inductive, inductive, and non-inductive with auto trigger, it is designed to meet the diverse needs of electrical and industrial testing.Key
