What exactly does the option to "Calibrate Power Supply" in the DC model do? I can't find any documentation on it.

Some people complained that the SMART DC units input voltage was not EXACT as there is a +/- tolerance.

So with the SMART DC models you can calibrate the input voltage to be exact.

A quick "search" for the word "calibrate" provides a list of posts that describe exactly what it does.

AFAIK it does not affect any switch function. All it does is adjust the reported value to match what you might be seeing from your solar charge controller.
