It works as a digital probe as well, changing to orange when a "high state" ( >2.5 V) is found.
To read voltage: hover probe over wires or pins to see voltages at any point of the circuit.
You can connect it with a wire to any part of the circuit as well.
To get available options Right-click on probe for context menu:
