I have been reviewing the emontx electronic scheme (to better understand its operation), and I have found several issues that I would like if someone could clarify.
-
I have seen that there are 2 burden resistor in parallel … is that correct? Is it to get a non-standard resistance value?
-
In the connection to the ADC pin there is a resistor of 1k connected in series with the burden resistors, what purpose does this resistor have?
Thanks!!!
