Stecke die schwarze sonde in die com oder negative buchse und die rote sonde in die v oder positive buchse stecke dann die anderen enden der sonden in eine steckdose und lies die anzeige am multimeter ab. Start by selecting the corresponding current on the multimeter and a voltage range higher than the current you re testing. In this video i go through the basic functions of a cheap multimeter i cover how to measure ac and dc voltage how to measure resistance how to test for co. 1 x fonte de pesquisa as marcas na escala do mostrador podem ser de cores diferentes.

Uma superfície espelhada mais ampla. Then set the multimeter to the kind of voltage you re measuring if it doesn t have an auto range function. To measure voltage you have to connect your multimeter in parallel with the component you want to measure the voltage. Cada cor determina uma faixa de magnitude. To use a digital multimeter to measure voltage start by putting the black probe in the common terminal and the red probe in the terminal that s marked for measuring volts.

The black test lead connects on the ground side. For example if you re measuring the voltage in a 120 volt wall outlet. Localize o mostrador do seu multímetro. Read the value on the display. Your multimeter might also have a dedicated setting for testing the amperage of aa aaa and 9v batteries.
