I had this on an ultra-cheap Richmeters RM102Pro (Aneng 113D). It pissed me off. With Brymen, it might be a random issue, although having a fellow youtuber go through this as well is concerning. Perhaps it is a variability of part tolerances? |

No two model meters will be idential here is you are dealing with capacitive loads. |

I have been through many multimeters of several brands and the RM102Pro was the only one that gave me random beeps that I can recall. And I have used and tested many crap and excellent models/brands. |

there is nothing wrong with the 3 different boards i tested this meter on. . im not fixing damaged board. i am looking for Pinouts to Read MCU. on Boards. where do i get support for BM786?? the false beeps are very annoying . |

I'm not saying it's not a thing, but no one else has reported this, and I am not in a position to test this at present. Do you have the BM786 and are getting the same problem? Also, and issue on the Bm786 will almost certainly be present on the other models in that series. |
