plzz tell me how to check a mic with multimeter ?
Set your multimeter on continuity rang 1X , put red prod on center of mic (+mic ) and black prod on body or negative , its will show some reading , its healthy now , after that check its shortage, change your prods and vice versa it , now it will show high resistance, mean needle will not move, now confirm you mic is healthy .
plzzz also tell how to check a speaker
By using analog multimeter , select rang 1X for continuity, put any prod at any terminal of speaker ,put one prod constantly at any terminal , and touch other prod to remaining terminal of speaker try to listen click form speaker, a clicking sound can be hear. its mean you speaker is working , and meter will show speaker ohm too ,Quote:
