So to give a full scale deflection of 10 V for example the meter must have a resistor in series with it of value 10 KΩ, and measuring a voltage thus involves placing what is in effect a 10 KΩ ...

In addition to the measurement symbols, one symbol you must always be aware of when using a multimeter is the Ground (GND) ...

A multimeter is an easy prospect ... Where the meat lies in this project is in the ADC and its associated voltage reference, and for that he takes a surprising turn. Instead of taking an off ...
