I am having a problem measuring the Hz output of my 555 circuits.I have a fluke 88 multimeter,it has hz,and duty cycle functions.The problem I am having is that when I touch the leads I get a reading like 60Hz or so for 1 second then the meter reads zero.But my frequency is nowhere near 60Hz in the first place.Sometimes I get a Hz reading while touching only one lead of the multimeter to the output of the 555.Is this a common problem with these or could my meter be overloading the 200ma rating?I wouldnt think so but I am not an expert either.Any help is appreciated.
