Product Description

Among its features Using a 28" digital tube, voltage and current are displayed in different colors simultaneously Powered by an external power source Connectivity is protected with reversed connections. You are invited to download the technical specification document of our product on the Technical Specification page.
Using our 10A volt-amp power meter requires no extra shunts because of the built-in shunt there is no need to purchase other shunts
* Voltage to work with 4 of the *DC No power input can exceed 30V (the maximum input voltage is A burned meter will result from failure to do so) A range of voltages is available when measuring voltage The DC value is 0 A 100-volt connection Range of measurements currently in use The DC value is 0 Tenth A
Please read *Applications For monitoring the voltage current of batteries in automobiles, electric vehicles, or motorcycles, as well as for measuring voltage and current for other products
This package contains 5 v amp meter with cable that measures current at 10 A. There is a fee of 3 cents per unit. The cost of using it is low

Questions & Answers

Unless the display is totally isolated from the circuit that is measuring voltage and current, is the power required to power it separate from the voltage and current being measured?

The power supply and the voltage measured on the negative lead are In order to measure the electric current through the source or the load, it must be run from the negative side. If you have a multi-voltage power supply, it is impossible to measure individual current loads. Measurement can only be done at the combined total current of all the voltages.

I have a question only for the seller. Does this product come with a warranty against manufacturer defects?

Whether the product has a warranty is unclear to me. In the event of one of mine failing, I just bought 5 more and kept the other 4 as spares. There is no need to worry about their cost.

An inverter that converts 12 volts into 300 watts is powering my speaker and MacBook from a 12 volt outlet. It seems like this would be a good way to test how many amps the 2 devices are actually using?

Up to 10 amps can be delivered. I'm not sure if that product has a fault protection feature to protect against high current faults. 12V 300W Inverter can produce up to 25 amps. You'll need to put a lot of load on it to get 25 amps. Seeing what your devices' specs say can help you make an informed decision.

If the shunt is changed to read one amp, will the maximum amperage for the system be displayed? What are your options for a meter that measures mA?

Please find below a volt-amperameter with built-in current meter that can measure currents of the following ranges The 05A*10A formula. A shunt is not necessary to connect it.

I had no problems getting the meter to work and it was easy to set up
5/5

I found the installation and use of this easy. One commentator pointed out that the directions are lacking A few notes have been added to the diagram that is part of the product description in order to make it easier to implement. It wasn't clear to me at first that I would be able to install the meter in the panel cutout because, at first glance, I didn't see how I could compress the tabs sufficiently to fit it. To resolve this, I removed the electronics from the case and reinserted the case. I placed the electronics back into the case after that. In the case, there are tabs that fit into a slot on the board. My solution was to pry the PCB away from the case and then I was able to remove it - I used a small screwdriver for this. If you want to reinstall, you need to reverse the steps.

Although they work, they are not so bright and a bit fuzzy and have no instructions
4/5

You will not find instructions here. The Chinese aren't even fond of the tiny ones. As they should, they work well. of the problems is that the plastic shield near the led digits causes the output to be dim and blurry. a positive note, the shield can be removed (not really needed) and both the voltage and current sections can be individually tailored to one's needs. As a set of five-digit multimeter and very accurate voltage standard, the accuracy was a certain acceptable and usable for the price, however I was able to adjust to be more accurate with this than with my voltage standard (of course Typically, these units are not required to be hyper accurate since they are primarily used in power supplies. Furthermore, the circuit board can also be separated from the casing if you prefer. Despite all of that, they are an excellent value and are well constructed. Videos explaining how to do this It's good to watch four to five of them and make your own diagram, as I did, because some are incorrect and some are poorly done (too many amateurs).

This measurement is taken on an unisolated surface
3/5

Interference with complex circuits is a serious problem. The reason for this is as follows. In other words, the ground is the lead of measurement. There is an internal ground connection within the device. If you were to run bucks or anything off the same battery and then these off the battery to measure the CC output at the bucks, then the ground would be connected. Then the fire burned them up. This was due to the fact that it included After burning the second and thinking I had miswired, I threw the burned 2 into the trash. It appears that the wiring is okay. So I checked it. Rechecking each wire, I verified that each one was specific to that wire. It did not work the second time, so I tried Once again, it was burned. This measurement problem has to do with the fact that it doesn't measure A common ground is cut off from each other. In addition, an anomaly occurs when bucks are running because they are intrinsically linked. As it turned out, I was able to get them working by using an isolated buck to supply power specifically for the gauges. When it began interfering with Bucks CC, it was a major problem. Leaks that occur in a non-isolated environment originate from whatever is going on inside the curcit. Resetting the capacitor with a multimeter gave me the same result. I guess all in all, it is a good thing. To make my end product work, I had to go to more advanced units that were indeed isolated. If you are building anything complicated that needs to go through converters, please tread carefully with this product.

An old battery charger gets a new lease on life
5/5

Amp meters were analog back in the day, but they were killed The new version is better than the old.

For projects, good panel meters are needed
5/5

The project I was working on required five meters, which could calibrated on the voltage and current to show the voltages in relation to each other. These meters could be calibrated using the voltage and current to be accurate and to be able to monitor 5 different voltages at the same time. There is no way to test the current on each separate voltage as the amp meter is only connected to the negative supply line. Using just one of the AM meters, you will be able to see the total current across all I can use one amp meter for each power supply between the negatives on the power supply and the common on the load because I have two power supplies.

Taking the easy way out is the right choice
5/5

The items are sold by a number of companies. I was able to get what I was looking for from this seller. Your job is going to be packing and shipping. It's likely you already know what you're doing. This is a right action on the seller's part. Please let me know if you would like me to review a product. You're out of luck if it doesn't work. My call to action is to.

The price was great, the display was easy to read, and only one of five failed to function
3/5

On my small solar system, I used the volt meters to measure the voltage of four batteries. After two weeks, the fifth meter, which reads the total voltage of all the batteries, failed (the wiring of the fifth is different than the others because it reads over 30 volts). As I write this, I am in the process of replacing a All in all, I am very happy with the display and the design. The other 5 meters will be ordered in case of failure of the first ones.

It worked like a charm
5/5

This kind of video is the best I've ever seen. These products have been purchased before and have worked perfectly for those projects. The manuals do not contain instructions for hook up, but you can find them online.
