Connect the voltmeter in parallel with the circuit being measured. No current flows through an ideal voltmeter.

The meter below is nice because you can see the inner workings.

There is a magnet and a spring loaded coil. Small currents through the meter magnetise the coil and cause the pointer to deflect.
