Hi there,
I’ll take that as a Yes. (and you can still go fix it, the cut & paste to </> just click it and paste your code there super easy. 
)
this is the proper use of the code tags, btw

read the notes this was configured for a UNO originally?
Note, the default current is only 1.3A so be sure to set your range somewhere in the middle, I have seen it used to monitor a E-Golf Kart Battery of 36Volts a while back if I recall it worked very well.! Do use the Multi-meter in line (amps) mode to calibrate after you have a handle on things to get the most accurate reads, and yes the first one can be ZERO. it’s in the data-sheet.
I’ll find the link to the white paper we used as a guide time permitting.
