    Good accuracy in measurements for its cost, relatively slow in final display when measuring in Auto scale.
    The only problem is in continuous measurement, where it measures and beeps, stops and measures again and beeps, which of course confuses you and makes it impossible to be sure.
    The problem is factory-related and affects the entire Uni-T UT139 series,
    you will find several videos with reviews that mention and show it.
    I have also uploaded my own video showing the problem.

    It does the job it's supposed to. The sampling rate is relatively fast, maybe personally I wanted it to be a tad faster.

  • The instrument was purchased two years ago and although it worked perfectly at first, for the past 5-6 months it has been affected by humidity, maybe because it is not that high (around 60-67%), and it shows resistance non-zeroing in the beeper position, and in the capacitor measurement position it also does not zero.
    I am not satisfied with this and of course I do not recommend it.
