Sluckey's version with model -061 does in fact work like a charm. Thanks. I knew I should have bought that one in the place.

Y'all got me interested in adding a meter to my old vatiac. So I got the PZEM-061 model that uses a current sense loop rather than a built in sense resistor. The wiring is much more straightforward than the wiring for the PZEM-021. I did the zero mod on mine and it works very well. Here's a short p...

So for me, the backlight is flashing, but the entire display turns off around 100VAC output. I'm just going to undo the mod for now. Not sure what's going on, but I agree with ChasW, it's not that important to me to see those low voltages, and I have a bulb limiter to limit current anyway. Is your ...

I also can't tell if it's just the blue backlight flickering, or the entire display. Quickly push the button to turn the backlight off/on. So for me, the backlight is flashing, but the entire display turns off around 100VAC output. I'm just going to undo the mod for now. Not sure what's going on, b...

What sure of enclosure? Desktop or rackmount?

I performed this mod today per the schematic and details posted above. The schematic made sense, the video not so much. First I did the 4 wire hookup to meter and it worked as expected with panel powering up and working at around 45v and was good all the to max 145vac. After that I did the full Mont...
