If you are a do-it-yourself kind of person, you know that performing your own home repairs can save you a lot of money in the long run. If you are doing your own electrical work in your home, you will need a multimeter to help you identify what wires are active and how much power they are using. The Micronta multimeter is one model that you can use in your home that features a digital display for quick reading.
Set the function dial on the multimeter to the setting of the electrical current you wish to read. If you set it to "Volts," the end result will be displayed in volts, while "Ohms" can be used to read the final result in ohms. Volts will be used most of the time, but ohms can be used to get a more accurate reading.
Press the "AC/DC" button to select the type of current that you want to test. AC is the type used in the U.S. and any electronic device that will be used there and is represented by an "AC" logo. DC is more popular in Europe and Asia and electronic systems and will be represented by a "-" symbol.
Touch the red probe to the positive lead of the circuit you want to test once you have selected the settings. Carefully touch the black probe from the multimeter to the negative lead. Do not mix up this step as doing so could lead to an incorrect reading or damage the circuit.
Wait for the power output to show up on the display. The number may change in the first few seconds the circuit is connected, but should eventually stop on a specific number. If you see a "-" before the number, you have selected the wrong current type, or have used the leads incorrectly.
Do not attempt to measure a circuit that holds more than 400 volts as this will shock you. When you measure voltage in a high-voltage circuit, do not try to position both probes at once.
