Technical question: is any sort of smoothing or averaging done on the input prior to display?
Example: voltage fluctuates between 13v and 14v at a frequency of 1hz. What will be displayed? How about at 60hz?-------------------------------------------------

I know you're a bright guy, but I just have to dish it back...
You do know that the defining difference between AC and DC power is not alternating voltage between two positive values, right? DUH.
Of course it's DC. I'm not asking what happens if the current alternates at 1hz, I'm asking what happens if the voltage alternates between two values. Does the display become unreadable as it changes values 10 times a second? Or will the display not show spikes?
Now, perhaps it's a silly question because the battery acts like enough of a capacitor to smooth out any sharp fluctuations (and the wiring is good enough to allow the battery to do that). I don't know a lot about the electrical systems of cars, and if that's the case you may dismiss my question (though at that point it doesn't seem like a "Duh" question).
What I do know is that I've built similar components for other electrical systems and if you were trying to detect fluctuations you had to be mindful of the frequency of the fluctuation you were trying to detect, so that the display was readable but the spikes weren't smoothed over. I've read enough about what you do, to know that you understand that. What I was curious about is whether the builder of these components took that into consideration.-------------------------------------------------

These do not detect rapid spikes....if that's what you're askingComment
