Enhancing a simple handheld multimeter

Fons Janssen, Maxim Integrated

Simple handheld multimeters often have two inputs for DC current measurements. One input is usually for ranges up to 200mA and the other is for high currents up to 10A or 20A. There is no 2000mA range. So if you need to measure currents in the order of 250mA, you need to use the 20A range, which offers limited ac
