Absolute zero

[urosv]

Is there a solution to the data shown by Inp4 and Inp5 when nothing is attached. Both inputs does not show absolute zero or empty value when there is nothing on so you cant absolutely know is there a problem with sensors or with LAN controller.

PT selection (Inp4 = N/A and Inp5 = -3.24)
SOLAR selection (Inp4 = ~507 and Inp5 = 2.14)

If nothing is plugged in to input INP4 = N/A and INP5 = 0. What VCC supplay you use?

Ja mam podobny problem z jednym z LK, mianowicie na Inp5 mam 0.02 A mimo, że nic nie jest podłączone pod to wejście. Cały czas taka sama wartość. LK podpięty pod akumulator 12V.
