    Great product, very useful if you need a simple voltmeter. I was looking for a product like this for months, but I found just car voltmeters. Looks like a professional product, you can install it in a professional power supply and sell, good presentation, no scratchs or failures on injected plastic.
    This product could have some instructions, for example: what is the trimpot for? What is maximum and minimum dc power input? And about range, could be 0 to 19.99Vcc? If we could change dot position (with a simple jumper), this meter could be used in much more applications.
    I really like this product, I recommend.

    Nice color, well build, smooth dial change, looks like reliable design of the lock itself. Comes very well packed, so may be used as good gift for biker.
    simple thing, nothing to wish above it is.
    this was the firs thing I bought at DX without reviews, and I'm happy I didn't make a mistake. Buy it, this thing worth your money, especially it costs only 10 bucks.
  • Great choice for those who don't want to spend

    It's a great device for those who doesnt want to spend much and need to solve problems quicly, but you might be surprised with the instructions manual, because you have to almost uncrypt it.
    I think this device should receive a better manual. And the build quality could be a little better, because it came with no box, and that could damage the product.
    If you like to spend a little bit less than expected, and you want to brake your head trying to read the manual, this is the right product for you.

    As plus I will note easily to use. I wanted to buy for a long time such tool compact and effective. Starts to check the motherboard already after inclusion shows a code of a condition of the motherboard.
    In the complete set there is an instruction on use of the device of it more than enough to start use.
    As a result I want to write that the device approaches for the house and work when do not know why the personal computer that this device that is disconnected that is necessary for check.
  • Time counter

    Nice, big and bright LED-display. Counts seconds, minutes or hours (choice is made through a jumper on the back). You can choose whether the unit zeroes itself or not with another jumper.
    The connection is as follows: short V and A; the count begins. If you don't set it to auto zero, the value will stay on display until you short D and GND or if you power it down and up again.Datasheet can be found by Googleing for um5140tu-a1
    Nice module and if you want to keep track of how long something's been up while it has power, this is a unit to go for. Does not retain its data after power down.
