1. It can measure both d.c and a.c voltages.
2. Responds instantaneously unlike ordinary meters because the electron beam is weightless
3. Can measure large voltages without being destroyed
4. It has a very high resistance and does not therefore alter the current or voltages in the circuit to which it is connected.
