In Part 1 of this article, we saw that one of the basic methods by which a digital measuring device operated was the conversion of an analogue signal (often a voltage or an electric current) into a set of digital bits. The number of bits determined the precision with which the device could take a measurement. The article went on to describe the workings of a digital thermometer and how domestic-quality thermometers are often designed around the use of degrees Celsius with displays in degrees Fahrenheit being an add-on where the Fahrenheit display is calculated from the equivalent Celsius measurement.
In this article we will look at how digital weighing devices work.
