Digital Volt Meter AKA DMM Digital Multi Meter
The advantage is no needle on the meter to get damaged, usually better
accuracy and no load placed on the circuit you are measuring.
The down side is since the meter does not load the circuit, stray voltage
will make you think the circuit has full power but it does not. If you are
measuring battery state of charge, a oxygen sensor or other computer car
sensor,
the DVM is better. If you are just trouble shooting a wiper circuit, a test
light is better because it load the circuit.
