The exact function of the diode check can vary from multimeter to multimeter. A diode is like a one-way valve that only lets electricity flow in one direction. Some multimeters also have a diode check function. You can also use it to make sure two things are not connected, to help prevent short circuits. This is helpful if, for instance, you are building a circuit and connecting wires or soldering the beep indicates everything is connected and nothing has come loose. Some multimeters have a continuity check, resulting in a loud beep if two things are electrically connected.

See the next section for an explanation of what these terms mean, and click on the Using a Multimeter tab, above, for instructions on how to make these measurements. There are many different multimeter models visit the multimeter gallery for labeled pictures of additional models.Īlmost all multimeters can measure voltage, current, and resistance. Below is a picture of a typical multimeter. Most multimeters have a knob on the front that lets you select what you want to measure. The neat thing about a multimeter is that unlike a ruler, watch, or scale, it can measure different things - kind of like a multi-tool.
