You only need to adjust some controls, like the tempo slider, the beats/bar spin box and the rhythm figure selector. Press the play button to start. Use the stop button at your convenience.

Tempo can be set from 25 to 250 qpm using the slider. The units are quarters by minute (Mälzel Metronome units). You can also double click with the mouse over the main window to open a dialog box where you can enter a new tempo directly with the keyboard.

Beats/Bar can be set from 1 to 32 beats. These are the number of beats on each measure or bar, and it is the numerator on the time signature as it would be notated.

The rhythm figure is the denominator on the time signature specification, and represents how long is each beat. Changing this figure doesn't change the meaning of the tempo units.
