Continuity testing is useful when checking for any solder bridges or points on a circuit that shouldn’t be connected. We can easily check this by selecting the option and touching the probes together. Confirming that there is a connection between the probes via an audible beep, or LED light.

It checks for continuity between two points in a circuit. A continuity test is a very useful tool.We can use this to test LEDs (Light Emitting Diodes) before placing them into a circuit. The multimeter sends a little voltage through the diode, and displays the voltage drop on the screen. The diode test feature enables us to check the status of a diode.If these markings are hard to read, or misprinted we can use the multimeter’s resistance test function, Ω to check the value. Measuring resistance: Resistors, components which restrict the amount of current that a component can consume, use a color coded system to identify their values.

Most multimeters will need one of the probes to be inserted into the corresponding port, and remember to swap them back when done. Some more precise models can measure microamps or lower. Most multimeters will be able to measure milliamps and Amps. Current is measured in Amperes, commonly referred to as Amps. Measuring current, the flow of electronics in an electrical circuit, is another basic but important feature of a multimeter.Sources of DC voltages can be batteries, laptop power supplies and solar cells. But do not use your multimeter with high voltage AC outlets unless you know what you are doing. In a normal household environment, the most likely source of AC voltages is your outlets.

Measuring voltages is one of the most basic features of a multimeter and we can measure AC V⏦ and DC V⎓ using the same probes and multimeter.
