The R-­500-­L shunt resistor is a precision Cu-­Mn resistance. It consists of two force and two sense contacts for conventional four-­wire measurements.


The shunt is designed for precision current measurement in instruments, industrial,and automotive applications, typically including energy meters, power inverters, battery current monitoring.
