Most shunts are made of a manganin alloy, which consists of 84% copper, 16% magnesium, and 4% nickel. The alloy has a very low temperature coefficient of resistance, and the resulting resistance is less than 0.1 ohms. The voltage drop at full-scale current is about 50 mV, which means they have lower power dissipation and less self-heating than copper.
Shunts can be connected to more than one location, so multiple meters can be connected to one shunt. This type of configuration is helpful for monitoring current at multiple locations. For example, one shunt can measure the output of the alternator in more than one location. Since meter currents are very low, they can be easily monitored in many different locations.
is similar to a T valve, diverting water to another pipe. A flow rate meter can measure the flow of water through the bypass pipe, which can then be used to measure the resistance in the main pipe. This is a convenient method for monitoring current in a wide range of applications.
Meters are also useful for measuring voltage. DC ammeters require shunts in order to work properly. They are available with built-in or external shunts, and should be matched to the circuit where the current is to be measured. Shunts also require calibration.
