Set it up to use on a 3.3v, 5v and 12v supply but the Ammeter only works with 12v. Voltmeter works fine on all 3. All are linked through the same connections to the ammeter.

I am an electrical engineer with extensive experience in digital electronics. I used two of these meters to replace defective analog meters in a power supply. I found the connection diagram easy to use but both meters in the 2-pack are showing incorrect voltage and current readings. After much searching for documentation I discovered that when connected to a power supply using that power supply to power the display that the thin black wire must be left unconnected. With that fix the two calibration adjustments worked.

I have used these on various projects and they work very well. A very good value.
