Greetings to the colleagues of the forum
Be sure to get this accurate 5-digit digital ammeter module for your work. It is very effective. You can meas
It worked very well for me... the amount of charging amperes, types of batteries, amperes, smd led chips, power supply, sensitive and accurate, it
really works.

do you have a question here? Or is this just an endorsement of a product, an endorsement of a technology or an advertisement?

To me, it looks like a Vellman style meter that typically have trouble with three digits of accuracy because they do not use zero temp coefficient burden resistors or compensate for temp in any way.

It is not an advertisement of a product, because I did not mention the name of a specific company, it is only a suggestion and confirmation of a product, which is considered an important tool for accurate work.
Now the question is, can the amperage be increased to 10 amps? how is it possible?

You would have to modify the shunt, and rewrite the code for the
G factor of the shunt to get correct display. Or if not a processor
look at datasheet for measurement IC to see how range is handled.

And just how accurate is it?

What is the products accuracy specification? What does it use as it's internal reference? How stable is that reference's initial accuracy vs. it's drift over time and temperature?

Please be aware that having many digits of display may give you fine resolution, but not necessarily fine accuracy.
