Question 1

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.

Accepted Answer

Try contacting the customer service center.

Question 2

hi, which is the value of the shunt resistor of the amperimeter?

Accepted Answer

yes

Question 3

for the battery of a car will be useful?.

Accepted Answer

Working voltage: DC 4V-28V

Question 4

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??

Accepted Answer

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.

Question 5

What is the minimum current these meters can display  - 0.001A?

Accepted Answer

No it can not. Minimum current sensed is 20mA at best...

Question 6

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?

Accepted Answer

If each one is the same problem, I suggest you check the wiring

Question 7

can it measure current under 100ma?

Accepted Answer

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.

Question 8

please send me a schematico diagram about connection. thx

Accepted Answer

Sorry, we can't provide schematico diagram about connection, but the details page has a connection diagram for use.

Question 9

Does it have DOA Product Guarantee?

Accepted Answer

I think that is no DOA Product Guarantee,but it is safe.

Question 10

posso ligar ele na corrente alternada 127v

Accepted Answer

Dear,Working voltage: DC 4V-28VCan not work under AC 127V, otherwise it will be damaged.
