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 Features:Resistance measurement range of 0 to 2500Ω with a resolution down to 0.1µΩ.Adjustable test currents from 10A to 1mA for flexible testing.Internal memory stores up to 1500 readings, sorted by object and test index.Pt100 probe for temperature compensation and stray voltage compensation, ensuring accurate readings in varied conditions.Three measurement modes: non-inductive, inductive, and non-inductive with auto trigger, catering to different types of components.Basic accuracy of ±0.05% 1µΩ using the four-wire measurement method with current reversal for high precision.User-friendly interface with a large, backlit LCD display for easy operation in all lighting conditions.Audible alarms for high and low threshold settings for safety and convenience.Leakproof and robust design rated to IP53 and Cat III 50V, offering durability in demanding work environments.RS-232 connectivity for downloading data to a PC and performing advanced analysis with optional DataView
