Measuring devices serve to make different tests on components or machines.
There are a many measuring devices :
- first : The multimeter is the universal measuring device for electrical trades. It can check the ( volt -> V ) alternating tension and direct current. It can also test the resistor ( ohms -> ? ) and the intensity too ( ampere -> A )
- second : An absence of tension tester is useful to know if there is a presence of voltage in a circuit. It is mainly used by electricians because it’s a practical device. To perform a voltage check, insert probe tips in a power outlet or electrical panel (in a breaker circuit).
- third : The oscilloscope allows to visualize the frequency of an electrical signal. To visualize a signal on a good scale, it is necessary to take into account several characteristics.
