Just to be sure, you did use separate power supplies for each of them, right?

I did. The original power supplies that came with, plugged in to the same power strip/surge protector.

Some more diagnostics -- if I fully submerge the probe, the ORP jumps to 550 and stays there, and sometimes even displays gibberish. If I submerge the bottom inch or so of the probe, it measures ~ 270. If I slowly increase the depth of the tip (yeah, I couldn't think of another way to word that), the measured ORP value increases.

Leave just the tip submerged and report back if everything works as intended.
