Hi fellas, thanks for the input, it all helps.
@ Harvey;
Nicely outlined. You've helped clarify a few things which weren't so clear. The feeding a 50% duty cycle signal shall have to wait. My intention right now is to nail the technique in finding shorts by analyzing the millivolts
One more question, would be, "how might one find out if the tester has a high impedance?" There is no mention in the manual.
@ Aldue;
Yes, an infrared camera is definitely on the horizon, in fact, I do have one back in Europe.
Has anyone ever tried hacking a 'normal' digital camera by removing the IR filter lens to see if the components glow when hot? That might be my best option here.
@ Ed Breya;
I'm currently in Rio, so obviously have access to lots of LIA's... What color were you thinking?
No... apologies for being silly, but don't have access to a Lock-in Analyzer, tbh I have never heard of one. That said, I do appreciate the input and shall look further into them. My goal is ultimately to fault-find as quickly as possible, regardless of which technique or apparatus is used.
I'm still a hobbyist so still accumulating tools and testers. The reason for asking about the millivolt method in particular was that following a prior thread, it became very clear that it was something quite basic which was missing from my repair 'armory'.
Like Jim Ford however, I am intrigued as to recommended makes and models.
Appreciations to you all.
