Figure 3: Photograph of the Fluke 83V multimeter There are many different kinds of multimeter in common use (digital, analogue, pushbutton or rotary switches). Figure (3) shows the Fluke model 83V meters used in this laboratory. It is important to setup the meter correctly before use to prevent damage to the meter or to the circuit. To measure voltage and resistance simply turn the dial to the required position. The meter automatically chooses the range which gives the most accurate value. Current measurement often causes the most trouble. The ideal current meter has zero resistance, which means that if you put it directly across a power supply, you will burn something up. You must always put the current meter in series with the element through which the current you wish to measure is going. This means that you have to break the circuit and insert the meter so that the current can go through the meter as well as the circuit element of interest. Also, you need to make sure that the ‘+’ and ‘−’ terminals are connected correctly: when the meter displays a negative value, it means...
