Audio level measurement dB
The measurement way is like ACV measurement. When tested circuit contains DC part, it should series connect a blocking capacitor which capacitance is 0.1uF and withstand voltage is more than 500. Turn to range AC 10V, the fourth scale mark shows -10~22dB, and under other ACV range, the actual dBV should follow below ADD, dB form to conversion.
| ACV | ADD | dB |
| 10 | 0 | -10~22 |
| 50 | 14 | 4~36 |
| 250 | 28 | 18~50 |
| 500 | 34 | 24~56 |
