Ele possui uma escala em forma de arco e um ponteiro que indica os valores lidos na escala. How to use a multimeter. 1 x fonte de pesquisa as marcas na escala do mostrador podem ser de cores diferentes. 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.

This setting is usually denoted with the battery symbol. 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. Set the multimeter to ohms or resistance. Your multimeter might also have a dedicated setting for testing the amperage of aa aaa and 9v batteries. To measure voltage you have to connect your multimeter in parallel with the component you want to measure the voltage.

Turn the meter on if it has a separate power switch. The black test lead connects on the ground side. Read the value on the display. Por outro lado a corrente contínua é fornecida por pilhas e baterias. Use as funções de tensão para medi la em circuitos de corrente contínua cc e alternada ca.

Wenn du wissen möchtest wie du mit dem multimeter den widerstand oder ampere misst lies weiter. A corrente alternada é a forma de energia elétrica que você recebe pela tomada e alimenta o micro ondas o televisor a máquina de lavar roupa etc. Connect the com probe to the other side of your component. Again you probably won t even use half of the settings shown so don t get overwhelmed if you only know what a few of them do.

Connect the red probe to the positive side of your component which is where the current is coming from. For example if you re measuring the voltage in a 120 volt wall outlet. Uma superfície espelhada mais ampla. If you re measuring ac voltage place the probes across the component. When multimeter measures resistance in ohms it can not measure continuity because resistance and continuity are opposites.
