HOW do you tell AC or DC measuring voltage by the arc method ?

Cool, the link on top, is to a waste electronics seller that could email you
with all sorts new things to see, every fwe weeks.

You are interesting because you measure voltage by arc length
can you tell AC from DC ?

When I was real young, I tried to develop an electric Popsicle.
To this day I can measure 1V to 12V on my tongue with about 1 volt resolution.  Great for instant testing the condition of 9 Volt batteries.
I can easily tell AC from DC and usually determine polarity
that's which is the Plus and the minus lead.

How or where did you get that \$3 generator ?

Try shorting the blue teardrop device next to the output connector.

Those diodes are correct, You must have bought it when you got the notice.
Did you measure the AC output first ?

They only have 416 in stock :)
Can I get DC out of it ?

Sure make 600 VDC bridge out of 1N4005 diodes 1N4006, 1N4007 also work.
Don't forget a capacitor has to be 600 volt.

Sorry the unit output is only 400 VAC.
