Before performing any measurement it is necessary to know if the voltage is continuous or alternating, and then select correctly in the instrument the scale to be used.
It is recommended to start the measurement by always selecting the highest scale value and then lowering the scale until the appropriate scale is reached, which provides the instrument's maximum accuracy for the voltage level to be measured.
The instrument used to measure electrical voltage is called VOLTIMETER or multimeter, it must always be connected to the electrical circuit, source or with the consumer, in PARALLEL, for that there are used two tips one of red color and another of black color, these must be placed, positioned at the two points where it is desired to obtain the electric potential difference, electric voltage.
