very good product, very usefull in many projects, you can even use it to build you own dc current suplly, very satisfied, can buy it !

Товар пришел достаточно быстро! проверен работает на 100%

This is fine product, i would recommend you this because its not expensive and it is measuring kinda accurate. Its fine bright. As i know ... the small wires are used for some energy source ... and the big cables for measurment.(i dont know well, because i am begginer for DIY electronics) The con... This is fine product, i would recommend you this because its not expensive and it is measuring kinda accurate. Its fine bright. As i know ... the small wires are used for some energy source ... and the big cables for measurment.(i dont know well, because i am begginer for DIY electronics) The only con of this product is ... that there is no manual, so you need to test it yourself. Pros: Cheap, bright, accurate, well made Cons : No manual included Read more

Pros: Very cheap and very handy for the things it does. Cons: A segment of the voltage meter failed the first day so it showed that the quality is not good. It has 5 connectors, 2 for the voltage meter and 3 for the current meter but is not easy to discover which one is for the + current or for -... Pros: Very cheap and very handy for the things it does. Cons: A segment of the voltage meter failed the first day so it showed that the quality is not good. It has 5 connectors, 2 for the voltage meter and 3 for the current meter but is not easy to discover which one is for the + current or for the - current. Other: I bought just the voltage meter and it worked very well so I think that it is better to buy the things independently. Read more

[en]Nice, good-looking, colorful, can be easily mounting on rectangular hole in the panel [ru]Симпатичный двухцветный приборчик, легко монтируемый в прямоугольное отверстие на панели. [en]Cannot measure negative polarity so poorly fit to monitor battery status (without external commutation can show either charge or discharge current). Volts accuracy is fine but Amps value is strongly underestimated (my device showed 2.8 A at real 3.8 A) so I had to file the shunt using needle files. [ru]Не умеет измерять отрицательные значения тока, поэтому плохо подходит для мониторинга аккумуляторной батареи: либо заряд, либо разряд. Пришлось поставить переключатель полярности. Показания тока были сильно занижены: показывал 2,8 А при реальных 3,8 А. Был вынужден подпилить шунт надфилем. Read more

Pros: - Bright and cheerful - Accurate, agrees with HP lab supply to the last digit Cons: - No dimension data, could not make panel for it until it had arrived. Notes: - Takes a few seconds to "start up" - Update is around 5Hz from eyeballing it -

I bought 3 of these units. I have connected the 3 units in series to 1 power source to test the measurement precision at different V and A levels (See the attached pictures). Also I have drawn a circuit diagram how you may to connect meter... pros: cheap; measurement of V and A in separate cons:... I bought 3 of these units. I have connected the 3 units in series to 1 power source to test the measurement precision at different V and A levels (See the attached pictures). Also I have drawn a circuit diagram how you may to connect meter... pros: cheap; measurement of V and A in separate circuits possible. cons: accuracy of measurements is not too precise but very acceptable for monitoring V and A.

Great product. Very good tool, well finished, well visible LEDs. It is very stable during use. Fulfills its role well in both voltage and amperage indication. I'm satisfied with the product and recommend it. I have not found disadvantages in product.

PERFECT

Good price and very small. good for small projects. .
