I received the 400A AC UT-201 clamp meter just now. (20/02/2023)
It works as it should.
I will perform more tests, but for now, I am satisfied

Good quality construction for its price. However, it does not measure resistance accurately, like more expensive ammeters do. That's why three stars. I should have expected it. Essentially, you are buying a multimeter with the ability to measure AC current induction.

Quality and reliable so far. Worth every euro. I have compared it to a fluke in measurements and they are the same.

After a year of use, it is perfect. The only thing I miss is the ability to measure continuous current from batteries, which the UT-203, the next model, has but with a price of 45 euros.

At this price, there simply isn't anything with the corresponding quality. Don't make the mistake of getting the cheaper amperetongs to save 5-10 euros, because simply put, they won't do the job. They break very easily and don't show the correct indication when there are other cables nearby that you are measuring. I work with 3 of these and many people use one of them, and it hasn't had the slightest issue, it is very durable. If you want to measure current in continuous, you pay a little extra to get the ut-203.
