Volt Amp Meter, AC 500V 200A Digital Voltmeter Ammeter Panel, 0.39 Inches LED 2in1 Multimeter, 2-Wire Voltage Amperage Tester Gauge with Current Transformer

Handy little device. Works as expected and worth the value. Tested it against my good Muti meter and it was within 1 % on voltage and 1.5% on current.

Easy to install, worked perfectly out of the box, great looking LED display, bright and sharp, very easy to read from a distance. Very pleased, recommended!

The only issue I have is the wires are short and very small, but it does work great and has a well lit display.

so far these are working well, look good and appears to be accurate.. Hope they last.

The media could not be loaded. First off, kudos to the person who included the wiring diagram in their review. I was able to make sense of the one on the page, but that is a great simplified, concise version that was helpful and easier to view when wiring it up.I specifically purchased the 4.5-100VDC /0-50A meter. I do a lot of tinkering in general with circuitboards and DC voltage, but for some devices I would need to or may exceed the 10amp fuse on the meters I have that can measure DC amperage (and also, the ones that I do have some weird 10A fuse you can't just run out and get somewhere, go figure, lol)One such project was replacing the dead Ni-MH battery in an old cordless vacuum with something more modern and readily available. I found a power tool battery that would supply 24VDC and that was also capable of providing the needed amperage, which I'm running through a DC Buck converter with adjustable voltage and amperage. This meter allowed me to correctly measure the voltage and adjust the amperage amp by amp to insure I was only reaching the amperage the vacuum needed to run without going over. I look forward to wiring up a little 3d printed enclosure to install this into so I can use it more like a regular meter with my tinkering. Highly recommend.

This is a great meter. It is bright, and easy to read. The only con is it only shows amps in one direction. Other DCA meters I have show a + number for charging the connected battery, and a - number for discharge. When connected, this device will show battery discharge accurately, but to get a charge reading you have to swap the sensor wires across the shunt. It is really a great device. I recommend it. It is also a great value for a big super easy to read display. Easily read from across the room, unlike most others.

You can't beat the value of this meter. Comes with the shunt, Simple three wire hookup. I bench tested it, and it works great and is accurate. I will be building this into a test box for checking trailer wiring. I've used these products before and found them reliable.

No good. Didn't work correctly from rightout of the box , first time connected . CT wires to screw terms. Red and black to power source. Ammeter reading was faulty reading only a small fraction of the correct amperage as verified by a simultaneously measurment with a good and accurate digital clamp on meter. It was 2.71 amps on the good meter while reading only .05 amps on the same line load lead to this meter.
