I have professional devices, DerEE DE-5000, RuoShui 4091C, Miron m63 v3.4a
I 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 the
programmed values for different capacitances, and the presence of an "oscilloscope" in it makes this TS3 just a child's toy.
