I opened up the unit for you guys so you can see what's inside. The microcontroller or measurement IC's are underneath the display module so I can't tell what they are. The unit appears to be well-made and the soldering is OK.
The unit operates when the main power connector is plugged in and the power supply is turned on. If the 4 pin MB power connector is not plugged in, the unit will show, for the +12V2 voltage, "L.L" and the unit will beep. The beeps are very quiet.
You should only connect, at any one time, only one of these three power plugs:
SATA
Floppy (does anyone have a floppy drive these days?)
4 pin Molex
This is because they are all wired to the green LEDs at once and connecting more than one power plug at a time in parallel wouldn't mean much. This isn't explained in the documentation, which needs a second round of editing to make the operation of the device clearer.
The three green LEDs indicating 3.3, 5, or 12 V from the floppy, SATA, and 4 pin Molex power connectors are not an indication of a measurement "good" signal from an active device that is "measuring" the voltages. Rather, they are simply wired straight to the incoming voltages from the connected SATA, Floppy, or Molex plugs with a series current limiting resistor. It is not a "measurement" in the sense that the other voltages indicated on the LCD display are being measured. It is just a "dumb" indication that a voltage sort-of close to the required voltage is present, or that the wires are actually connected properly. The 3.3, 5, or 12 V lines could be off by a bit and the LEDs would still light up, but they would be brighter or darker than they would be with the correct voltage applied. You can look at the main LCD if you want to know the exact voltage coming out of those power supplies.
Also, this measurement unit does not load the power supply and draw a lot of power like a real operating computer will when plugged into the power supply. So, if the power supply has problems maintaining proper voltages operating under a load, this unit will not tell you that. But you could infer that problem if all the voltages showed OK using this tester, but the PC still won't run properly (could be many other problems also ...).

Awesome tester!!
Easy to use and quite informative!
Brian S.✓ Verified Purchase•August 14, 2023
Got it quickly. Just plug in as labeled, and it tests all the power supply outputs while displaying the main motherboard voltages. Easy peasy.
This thing saves lives

Diagnostic 10/10. Easy to use. Wonderful tool. Helped me find out my psu was broken. Borrowed another psu and it passed the test. Bought new psu and out of the box it was giving same error. So I'll be switching brands. If it weren't for this tool I would have gone through heck diagnosing a second faulty psu. I'll be testing them all before installing. Again. 10/10
