This ultra small volt gauge allows for a separate power source from what it is monitoring; meaning the gauge can read right down to 0V without shutting off. To connect this gauge simply connect the Red wire to a positive pole on an external power source, the Black wire to the ground pole of the external power source and the ground of the circuit you are monitoring, and the Yellow wire to the point which you would like to measure voltage (see attached diagram).

The gauge has two 2mm mounting holes spaced 26mm apart.
