These units are great... I have a version with the battery holder for a single AA lipo cell. (I hate 9V batteries). The cell charges when the usb cable is connected. I had several motor start and run caps die on my 20 year old Chinese mill. This tester checked the 65uF and the 300uF caps and told me in no uncertain terms that they were fubar. Upon dissection of the caps, several had vaporized the connections between the foils and the external wires. One looked like corrosion and a couple looked like bad solder joints. A few caps later, all the motors start and spin again.

Yes three terminal voltage regulators look diodes, I think.

Not being able to download PDFs would be annoying.  Best to just do a
delete/reinstall on the browser.

That PDF files is all you need.   Use "git clone" to download the file.

The other stuff on lithium is only useful if you want to understand how it
works or join the group of people contributing to the design of the next
version.
