Unfortunately, that's just the way it goes.
The cheapest models of meters (if you'll forgive me for calling them meters) are manufactured by dozens of different companies in the so-called Far East, according to their own ideas. The designation may be a matter of coincidence, or what kind of housing you managed to buy cheaply.
You can count on the lucky chance that someone owning EXACTLY the same meter will see this post and respond. But that's like getting a six in the totem pole. The chances are poor.
If I were repairing this equipment, I would carefully remove the burned components and try to draw a piece of schematic around this "problem", and then look for analogies among schematics of similar meters. With such a simple patient, it should work.
Tedious, thankless and unprofitable work - unless we are talking about gaining experience (then the time and effort spent is not in vain).
This is why I suggested looking at the schematic of a SIMILAR device (because, after all, you can see that it is not the same).
If you remove the burned components and carefully check what then in the meter does not work, then you may also be able to guess what should be there.
Of course, if the fault is only one and it is caused exclusively by this burned component.
All the time I mean didactically oriented activities, because serious repairs are not carried out in this way.
Hi.
