Maybe I wasn't clear enough for you , a laggy beep ( 0,5sec or more ) is not something good or normal . If a meter has the beep it should be as fast as possible so you can't feel a big lag , or you think otherwise or don't care ? Thats the issue with 121GW , I want the beep response in diode mode to be faster , not lightning fast but decent enough . The discusion about other meters , who has the beep and how is implemented is useless at this point . You can complain about that if you want something different .
And for sure this can be corrected in firmware with a little effort ... just one more small issue on the list
