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.

Nothere are no plates or anything, these are meant to snap into something that you provide yourself.

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??
Linea rossa sottile: alimentazione + Linea rossa (spessa): IN +, ingresso corrente Linea gialla (spessa): PW +, misurazione della tensione di ingresso del terminale positiva Linea nera spessa: COM, misura comune ma ci sono due connettori, uno con tre linee fine gialla rossa nera, l'altro con due linee spesse una rossa e nera ??
plug de 3 fios finos, vermelho, preto e amarelo: vermelho é tensão de alimentação do voltímetro, minimo 5v, máximo 12v. preto é gnd. amarelo é leitura da tensão. plug de 2 fios grosso é a leitura da corrente de amoeragem:. vermelho e preto: preto é conectado a saida - da placa da fonte. vermelho será a saida out - (gnd) da fonte. o fio amarelo é ligado no output + para fazer a leitura da tensão.
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?

For me min. voltage i could get was 100ma.Dint forget it is not made for accurate and professional measures, it is for general daily help and quick visual display.
