Thanks for the instructions, that makes a lot more sense now. I was completely lost trying to adjust the upper and lower voltage for my battery setup, and it was stressing me out since I really needed the meter to show correct readings. On top of that, I had a paper due the same day and zero time to write it. I ended up using professional writing services https://www.reddit.com/r/BackToClass/comments/1mbhg88/writing_papers_after_being_out_of_school_for_a/ , and it was a lifesaver. The essay was delivered on time, well-written, and polished, which let me focus on the meter setup without panicking. It really saved my day.
