    Its working

    posted by mitrich80 on 04/18/2013 Certified Owner

    Involvement:General (knows how to use it) - Ownership:1 week to 1 month

    Pros:
    Very simple and quality product. You only need to connect two wires to a power source and make a hole for installation. The device measures accurately, but with a slight delay.
    Cons:
    Not really negative, but my device with blue numerals and not with the red. The brightness of numbers could be more intense.

    Good compact volt meter

    posted by mastertim on 04/10/2013 Certified Owner

    Involvement:Expert (understands the inner workings) - Ownership:more than 1 month

    Pros:
    it is lightweight and small. I think its accurate but i didn't test it actually. bright screen you can see it well. i think you can use this for much purposes and it can be used for a lot of voltages.
    Cons:
    make it can be cheaper but you dont hear me complaining about that. wires could be longer

    Pros:
    Very good indicator of voltage. The indication error is low, under 1%. The size of the numbers is perfect to be placed on a dashboard. The making power at the same voltage to be measured. Very convenient! It is very easy to use, just connect the two wires.
    Cons:
    I see no cons for this product...........

    Involvement:Expert (understands the inner workings) - Ownership:more than 1 month

    Pros:
    Small and precise, this device is able to measure with clarity and precision voltages of 3.2 to 30volts. Acrylic has finished on the sides allowing fix it at the source or even an appliance testing in electronic or electric vehicles.
    Cons:
    Nothing against the product delivers what it promises and I am satisfied with the purchase.

    Involvement:Expert (understands the inner workings) - Ownership:1 day to 1 week

    Pros:
    Easy to use. Almost constant current consumption (9-13 mA, depending on display elements in use) over voltage range. Relative error about +/- 0.1V over range. Better than 0.4% in 8-16V range.
    Cons:
    An average of 10.7 mA current draw may be a bit high for some applications, but this is not based on LCD! Above 17V the meter s...

    Involvement:Expert (understands the inner workings) - Ownership:1 day to 1 week

    Pros:
    Cheap and easy to use meter. Connect and read! Nearly constant current consumption over voltage, only depending on the number of LED display elements active.
    Cons:
    Precision a bit poor in low and mid-range. Shows 0.1 to 0.2 V too low up to about 15V. Relative error below 1.5% in the 12V bat...

    Cons:
    Not a Con, but consider where you want to put it first, some of the other ones on DX might suit your placement better. Designed...
