QJ31 DC single double arm bridgeThe portable DC single double arm bridge adopts a combination of Wheatstone and Kelvin bridge circuits. Equipped with a built-in zero finger and a wide range portable bridge with an internal working power supply. Suitable for precise measurement of DC resistance within the range of 100 µ Ω to 1.111M Ω in industrial and mining enterprises, laboratories, workshop sites, or field construction sites. For example, conducting temperature rise tests on the resistivity of metal conductors, cable resistance, shunt resistance, contact resistance of switches and electrical appliances, and the winding DC resistance of various motors and transformers.
