AD value of voltage
For example ,the digital display tube show “Cd”, it means AD value is
205.

Actual data/4.
If the value is higher than 99, the digital display tube will show single
digit and tens digit.
For example ,the digital display tube show “2.0”,it means the EXV
open angle is 120×4=480p.)
