I also sent an email to East Tester directly to see if they can assist.

Did you get any reply? In theory there is a compenstation function that seem to work on videos, have you tried it?

T3TRIS:
Oh I have not!! I didn’t know this was a thing (didn’t see a video). What I’ve done so far is use oversized wires and decrease the amperage toward the end of the test, which reduces the voltage drop. I’ll have to find that video, thanks!

I have one on order, since it was.. very attractively priced compared to the older version or even the DL24E in a resonable setup, so yet to test that myself.

So simple! Thank you for sharing. I’ll test it when I get back home.

Post some more pictures of the board with focus on the area close to the metal bars.  Shine a light behind the board to  see the traces. Most likely the voltage measurement is in the area of the op amps close to the metal bars.  There are probably some tiny traces going away from the bars area to measure voltage.
