Hello friends, I have a UNI-T model UT20B tester that is presenting me with erroneous readings, it began to show these readings after it was used incorrectly, they placed it on a voltage scale in continuity and measured alternating voltage, well it was what My brother said, although I think I use it to measure high voltage over 300 volts. I have a second Uni-T Model UT20B Tester that displays erroneous readings after being used incorrectly, they were measuring continuity in ohm scale or diode on an energized television board. The question is will it have a solution? Has any teammate of this forum repaired a team of this? greetings and thank you in advance for your opinion WhatsApp Image 09/17/2019 at 12.04.44.jpeg [49.80kb] WhatsApp Image 17/09/2019 at 12/04/44 (1) .jpeg [52.60kb]

Hi. What you can do is get a high quality tester and measure the external components associated with the micro. If all is well, the micro is corrupt. There is not much solution in these cases. Cheers
