  • nice display

    posted by prOOwner89

    I like this thing a lot, i had another one in red without the frame and it didn't look as good as this one, the blue color is nice and even, no dark sports, and seems fairly correct to me. The black surrounding around the display is made of the same material as most dashboards so could be integrated very wel in a dashboard without noticing. The display has a matte cover over it to enhance visibility in the sun or bright daylight.
    none
    This is the way to go is you want a nicely finished display with a case to match so you can build it in in something
  • Works great and easy to use and mount into panel

    Easy to mount into panels. Great size. The diffuser on the screen makes the characters a bit dimmed down, and not as bright. Perfect to use in boats or other places because it does not affect your night vision. Intelligent software adjusts the decimal point like: 9.99 to 10.0 volts.
    This voltmeter works prefectly in my boats cockpit to monitor my batterys. Works to what it is ment for.
    Easy to connect to battery etc. It is not much bigger than two AA batteries. Easy to read characters.
  • Excelent purchase. The precision is very good.

    Very good precision.It is a good choice to have it installed to monitor specific power rails in more elaborate projects.
    I miss a way to change the decimal point. If it had one, it wold be interesting to use this module to monitor higher voltages using resistance voltage-divider or even other parameters whose range isn't in the [0,100] range. For example, a pair fo resistors plus a diode and capacitor wold enable using this module to monitor the 127/220V power grid lines. In those cases, the dot mark in the wrong place is annoying.
    Very handy to monitor volates, but it wold be even more usefull if we coold handle the dot mark. Other than that, it is excelent.

    Voltmeter and Ammeter are very good calibrated. I tested it with my multimeter and it was fine 0.1 accuracy. Scheme is not correct. For real accuracy connector with a black and red wire must be connected to another power supply 0-30VDC. I use battery Ni-Cd 10000mAh. It is not possible to use it on same power supply when messuring volts and ammps
    Nothing special. Overell a very good product. Good visibility on display. Package came in one piece.
    Very quick delivery time.
  • Very usefull

    - It's bright - self powered - low current ( about 20 mA) - very small -good solder
    It works and does what it is supposed to do. My friends asked me to byu few devices for them too. So I'll by it again soon.
    Great produt for car, DIY projects, motorcycles and others.
