Build a circuit and measure the voltage

First of all, to have to build a circuit, we need some electrical components that we will need to do it.
For it, we need a stripboard (1), where we set the resistors, and the multimeter, using crocodile clips (2) to connect it.

When we have built our circuit, we have to connect the resistors to the current, using the crocodile clips. Then we adjust the multimeter and place the clips into the resistors. With the  manual adjustment  roulette function , select a range greater than it will be measured (for example 40 V), it will be displayed in the lower right corner of the display. Doing this, the display will show the legend "DC", "V" and the range chosen, in this case "40". It can be showed at the screen the sign (-), that means that the clips were connected in reverse.
This is the first step.
