content: Hello! FNIRSI DSO TS3 and TS2 do not measure ESR correctly or do not know how to measure it at all! Fnirsi LCR P1 - Does it know how to measure ESR and does it measure correctly?So the FNIRSI DSO TS3 and TS2 testers are completely inoperable, and are just toys. I would like to buy a normal tester, in a good case, which measures the ESR correctly, and not randomly like the TS3.Will the new tester have the opportunity to flash new firmware, and will you work on improving the firmware, or will you also drop the new tester like TS2 and TS3?

If you want an LCR, you should buy a real LCR.Shannon ST42 tweezers, DER-EE DE5000, etc. Will give you real LCR readings. People expecting $30 toys to do everything are being unrealistic.

content: I have professional devices, DerEE DE-5000, RuoShui 4091C, Miron m63 v3.4aI need a transistor tester, but since it has an ESR measurement mode, it should work.For example, the simplest transistor tester MTester LCR-T4 shows ESR measurements relatively correctly.I want the device in a finished form, in a beautiful case.But the previous FNIRSI DSO-TS3 device measures the ESR completely incorrectly, it simply substitutes theprogrammed values for different capacitances, and the presence of an "oscilloscope" in it makes this TS3 just a child's toy.

content: Yes, I need a transistor tester in a nice case. I will not measure the ESR with it.But since this transistor tester can measure ESR, then I would like it to measure more or less correctly.The simplest testers like MTester LCR-T4 can measure correctly.So I wanted to know if this LCR-P1 measures correctly, or shows nonsense like the previous two versions of FNIRSI TS2 and TS3.
