The function of the Manganin Shunt is to sample the current. It provides current sampling for the metering of the chip. It is actually a resistor connected in series (typically 380 microhms). When the meter is under load, current flows through the manganese-copper shunt and produces a voltage (mV level) in it. Computed with voltage sampling to measure energy.
A shunt resistor in a smart meter is a type of resistor that is connected in parallel with the current-carrying circuit, allowing for precise measurement of the small current consumed by the meter's electronic components, such as the microcontroller and communication module, which typically draws a small current and is separated from the main current measured.
Smart meters often have a built-in measurement circuit that includes a shunt resistor, which can be used to measure the small current that flows through the meter's electronic components, and the data is then used to calculate the overall energy consumption. The accuracy of the measurement depends on the quality and precision of the shunt resistor used. Smart meters often uses high precision low value shunt resistors, in the range of milliohms, in order to accurately measure the very small current consumed by the electronic components.
