How to Use:
1. Level Meter Debugging:
Find a generator, adjust the output frequency of the 1KHz to 0.775v, connect it to the input of the driver board, and point the pointer of the meter to 0DB on the instrument panel.
2. Debugging of VU Meter:
The adjustment of the VU meter is much simpler, the driver board is connected to the audio , and the adjustable resistance on the driver board is adjusted, so that the loudness and rhythm of the ear can be synchronized with the pointer, so that the pointer swings in a moderate range. 100% position or plate scale maximum.
