I've used a few different flavors of these cheap digital meters (0-500VDC,
120VAC, 300VDC) and have not had any problemsyet. Most of them are
self-powered, which is handy because it doesn't require a separate power
supply, though risky because they do create a potential source for a short.
I am a bit afraid of all those inexpensive displays made in PRC, the seller
often doesn't know what he is selling, the specs are wrong or trunked, and
I don't know their behavior with 300V DC or more...
Well, I ran a few of my IN-1, I had to run a couple of them at 4mA 180V and
the black marks
+1 for the Monty Python reference thanks Greg!

Next time I find a hopelessly stubborn item to solder, I'm going to get my
version of "The Holy Hand Grenade of Antioch" -- acid-core solder.
I've always wanted to know if the corrosive flux can be safely and
adequately removed, and possibly over-coated with rosin-based solder.
I rarely use
you should try phosphoric acid ( H3PO4 ) , it works great for rust and
oxyded copper.
if some black foam appears, that is the zinc (Zn) witch is dissolved.
it also stains stainless steel sinks.

Ditto on the stranded copper wire. One of the most frustrating things and
almost impossible to clean the strands well enough for the solder to wet and
make a reliable connection.
