Title: How it know? Again
Post by: joseph nicholas on March 09, 2017, 08:08:39 pm

I just bought a new multimeter (DT -somthing), just the cheapest.  Anyway, I was trying to test the buzzer by injecting some voltage into it and I blew out the LM358 soc dual op amp.  I removed it and powered up the meter, and guess what, it seems to work with the chip off the circuit board.

Why is this so?

5$ says the amp range won't work.   :D
