    Open mouth, insert both feet, chew vigorously........:D

    Egad ! I really muffed this one........I better pay attention to how to chase links.

    Even though, the ad does not list them as 0 - 20v meters...............whattheheck good is that anyhoo ?

    I had one

    It worked okay

    Then I broke off the connector

    It's not that accurate, maybe 1%

    Below 7V or so, the readings go crazy - don't trust it when the backlight is getting darker.

    ah, yes here it is:

    so there's a 50% chance that this could have covered 20% of his needs, had I posted it 1.5 months ago. It was a shot in the dark...

    If you could split the measurement input from the power input you could do more things with these. Even if they are not super accurate they are more accurate than inexpensive analog meters and are 10x cheaper.

    I take that to mean it simply measures its own power supply input voltage. A 2 terminal device. To monitor a car electrical system it would be great. I'd like to see its circuit diagram.
