      Just perfect. I checked the voltage readings against those of my very trusted multimeter ANENG 8002 (bought also from Banggood) and the difference in the range 1.2 – 33 Volts was less than 20 mV. Then, I checked both the voltage and the current readings against those of my RIDEN RD6006 power supply, and the measurements were almost identical (see photos).
      So, I have already placed another two of these in my shopping cart. Whenever you find something like this instrument, you buy some extra to keep them in stock. Most combined volt/ampere meters go up to 30 – 33 Volts, while this one goes up to 100 Volts. And it is both accurate (shows the correct value of the voltage / current measured) and precise (value presented with 4 digits in total, and up to 3 decimals depending on the measured value). Thank you, Banggood.

        Q: Why can't I write a review and add pictures to the review? I bought 3 meters on October 31 but when I click submit I get the message that I can't write a review for products bought over 6 months ago but it's just over a month ago when I bought this. I already tried to logout and login again but it makes no difference, the same happens when I try to write a review on my mobile.
        A:
        Try contacting the customer service center.

        Q: Thin red line: power Red line(thick): IN, current input Yellow line(thick): PW, positive terminal input voltage measurement Thick black line: COM, common size but there are two connectors, one with three fine yellow black red lines, the other with two thick lines one red and black??
        A:
        3-thin thread plug, red, black and yellow: red is supply voltage of the voltmeter, minimum 5v, maximum 12v. Black is gnd. Yellow is a tension reading. Coarse 2-wire plug is the reading of the milling chain:. Red and black: black is connected to the outlet - of the source board. Red will be the out - (gnd) out of the source. The yellow wire is turned on in the output to do the voltage reading.

        Q: I bought 3 units and each one suffers the same problem: the voltage displays just fine but the current flashes up a reading (correct) for about a second after powering up then the display goes back to zero. Have I got some broken modules do you think?
        A:
        If each one is the same problem, I suggest you check the wiring
