same as Va voltage which on label of panel right/top.
(deviation; 

±0.5V)

1) Connect + terminal of D. M..M. to Vs pin of P812, connect

-terminal to GND pin of P812.

2)  After turning VR951, voltage of D.M.M adjustment as

same as Vs voltage which on label of panel right/top.
(deviation ; 

±0.5V)
