Yes i understand what an Opamp does as far as amplify a small voltage or waveform into a bigger one, and the feedback resistor adjusts how much gain its going to be
What I don't understand is that, When I put my DVM probes on the input pins why is it zero volts or microvolts?
Are you saying that when you guys use an DVM meter and put your probes on the inputs of any op amp circuit it won't read because the DVM meter can't read microvolts so it say zero volts?
Is the inputs of any op amp circuit always like this? is this normal
My DVM meter can't measure microvolts, it can measure millivolts but when I put the DVM meter to millivolts setting it still read zero volts
Example:
When troubleshooting multiple op-amp stages lets say,
1.) Would the input pins always measure zero volts , microvolts?
2.) How would a Troubleshooting Tech, Know if the inputs were working or not?
3.) Because for me I can't tell if the inputs are normal/working because my DVM meter won't measure microvolts
Do u see my problem i'm having?
