As electrical energy prices continue to rise each year, accurate energy consumption monitoring becomes increasingly important. Therefore, there is a growing demand for high precision, low value shunt resistors in order to measure the flow of electrical current in applications such as smart energy meters and electric vehicle charging stations. This paper will discusses the concurrent trimming approach using machining to reduce the standard ±5% tolerance of 100μΩ Manganin shunt resistors which is used in metering applications. The experimental results reveal that the concurrent trimming approach can reduce the standard trimming time by more than 50% more than half the normal trimming time. The resistance value of shunt is obtained approximately at 100μΩ and is in the range of targeted value of 100μΩ with tolerance of less than ±5%.
