Wrong voltage calculation

[Luc3as]

Hi, I need your help,
I have very basic setup, wiring is correct, I found old closed issue about common ground.
I have power supply around 24 volts, 3 A, my module should be capable of measuring up to 3.2 A by the datasheet. but somehow if the voltage is bigger than cca 9 volts, I start to receive negative values.

I tried the very basic python sketch and this looks great so there has to be someting in the js library, but I could't find any problem.

I also noticed there is no change in voltage measuring if I change resistor value, in settings.
Don't you have any clue what could be wrong ? thanks

Thanks for your well documented issue, I'll check this out.

Was this issue ever fixed? With 18v in I see negative 15 on the node output. :-)
