It's amazing what can be achieved with a few (cheap) tricks.  :-+

Yes and it's a way to see if there's a problem with the rectification
bridge. if you have a not so good diode in the rectification bridge you will see it!
 but average mode is not good for signals when you can't get a stable trigger in this case hires mode could help better.

I'm on firmware 1.0
Any newer version available?

Thank you

Shame!!!

I don't know what Uout is.  Do you mean Vout?
If so, the device goes from 0V to 30V.

    "U out" is very commonly shown on German made electronics instead of "V out".  It must be a language thing. 

    This is the explanation that I found online.  One of our German members can probably tell us if it's correct.

But now, I found, an explanation plausible and maybe also a historic for that, which is as follows: Germans started denote voltage by the letter "U", probably because that letter was largely unused and so couldn't be confused with anything else. It also came up by its etymology, since "U" stands for Unterschied, which in German means "difference"; very fitting since voltage is obviously the same as potential difference.

"U" is not german. It is used  in europe overall.

As far as I know, "U" means “electrical voltage” (German: Spannung) and "V" is the unit Volt.
The "U" comes from the Latin word “urgere”.
It's like "I" ("intensité du courant") and "A" (Ampere).

In English "V" is used for the phenomenon (in formulas) as well as for the unit.
