BZ3-250 Ω type DC standard resistorDetailed product description：

BZ3 (250 Ω) is mainly used to detect unified signals at the output terminals of automation instruments and various power transmitters used in power systems.
BZ3 and BZ3C DC standard resistors, also known as laboratory resistors (single value resistors), are measuring devices for the basic unit of resistance (ohms). The products have the characteristics of high accuracy, small temperature coefficient, and good stability, and are the transmission standards for precision measurement and metrological verification departments.
