hello all, hello Don,

thank you for the explanation, it is that I did not think this factor

Thank you, I learn a lot with very interesting list, and big thanks to Don for us to share his knowledge.

Christophe,

The voltage that you see in the display will always be lower than the 
voltage at the input power jack.
There is a reverse polarity protection diode in the K2 and there is a 
slight voltage drop across the fuse.
That will make the voltage inside the K2 0.4 to 0.5 volts lower than the 
voltage of your power source.

73,
Don W3FPR
