The measurement is quite accurate, and the ADC reference is OK. Sorry I didn't
point that out originally. I did get some data from Gary, which shows that his
K3 current meter is much more accurate than mine.
The meter accuracy itself isn't really important, but the error may be limiting
Has anyone compared the K3 internal current meter to an accurate external
meter? My K3 meter reads about 20A, when the actual current is 23 A, with no
accessories connected. That's a huge error, and it's not linear.

Ok, when was the meter you consider to be accurate last certified? Or were you
taking the word of the meter on your power supply.. I am sorry, as a
former certification lab technician, I could not help myself.

And your reason for presuming the actual current at 23 A is . What
are you using to measure that? The meter on your power supply? A Fluke
meter that has a 25A range or ?
First calibrate ADC REF on the K3 CONFIG menu (TECH MD must first be set to
on) per the procedure on page 53 of the
