Hello.
I have jut got my first analogue oscilloscope. An Isotech 620 20MHz.
I want to learn how not to damage it, and I found instructions on the internet obscure.
They talk about ground, earth, floating ground, this, that....
But they don't actually say anything anything useful so far.
I want to know:
Don't connect exactly this to exactly there or it blows up.
For example, I am tracing a signal from a function generator in an audio amp, or testing for voltages in different parts of a circuit.
I want to know what not to connect it to. The instructions on the internet have no precise instructions and they were too general.
I have read things on the difference between negative, ground, and so on, and I still don't understand it.
Could someone just spell it out for me.
How not to blow up the oscilloscope.
I figured, just measure the voltage with a multimeter and check the maximum voltage and current rating for the oscilloscope before using the oscilloscope, but then the internet says something about ground that makes this idea seem useless.
Background on me:
I completed a short video course (~25h) on electronic repair. I have a physics BSc. I have dabbled in electronics since I can't remember, I have read a few electronics and radio books, but never took a proper certified course. I wouldn't say that I understand even 1/20th as much that a good electronic engineer does.
