Using a multimeter to check the electrical systems
Introduction
This instrument allows you to measure resistances, voltages, and current values. Multimeters can be
divided into two basic types: those with an analogue display and those with a digital display Units of
the first type are equipped with a dial and needle. The dial is marked with the scales to be used for
measurement of the various parameters. Digital units are equipped with a dial that displays numbers
corresponding to the values of the measured parameters. The type of measurement to be carried out
(voltage, current or resistance) is set by means of a selector or by means of several different sockets
in which to insert the two test probe connector terminals. In certain cases it is essential to set the full
scale value before proceeding. For example, in order to measure a 12 V signal, you need to set a full
scale that is close to this value (e.g. 15 V or 20 V). It would be illogical to set a full scale value of 10 V;
the same applies when setting current (Amps) or resistance (Ohms) full scale values. Sometimes the
instrument can set the required full scale value automatically. Never exceed the maximum value
allowed by the tester when measuring voltage or current signals.
