Thanks R_G_B_, it's indeed for electromechanical applications, based on motor... controllers.
But if I understand correctly your post, all these nice graphics require the Vantage graphing mm.
Which, correct me if I'm wrong, is actually a handy oscilloscope.
Which requires also, for current graphing, like most oscilloscopes, a "low amp probe" adding another ~$150 to the system.
Actually, I should have mentioned this earlier but as previously warned I'm more on the dev side. The pros who wander on this site and me may have different needs, in particular:
? the circuit may be cut to install a MM in order to measure current (no need of an external probe).
Thanks blueskull and I like the idea of using Arduino for sampling DC V/A (love C/C++ dev), but building a device myself...
better call the fire dept now...
Would you know any plug n play board based on Arduino (...) or connected to Arduino/other that (all DC)
• can bear 10A for measurement (or does some tricky electronics bridges to measure it without enduring the power)
• sustain 30V
• sampling at 20+ Hz
• sends collected data to USB (or serial), better real-time but even "after sampling" is OK if that makes it easier to find
Edit note: the "?" above is actually an arrow (unicode). The page being UTF-8, it seems the storage (mysql, files...) on this site is not UTF-8 or anyway doesn't store/load correctly the encoding coming from the page/DB. No complaint. Merely a remark.
