Transmission data description:
The conversion of setting and reading values is defined as following:
Actual value= Communication reading value × F actor (F value).
Among them Factor needs to refer to the definition of SCALING_FACTOR
in each model list.
EX: Vo_real(actual DC voltage)= READ_VOUT × F actor.
If the Factor of READ_VOUT of a certain model is 0.01, the communication
reading value is 0x0960(hexadecimal)→2400(decimal),
then Vo_real = 2400 × 0 .01 = 24.00V.
