I was hoping by buying a Fluke 771 that goes down to .01 milliamp ... that it would be helpful in the pursuit of stray voltage that can cause IC chips to crash. That is ... going beyond just checking for less than 1 ohm between a printed circuit board ground & the main electrical panel earth ground isolated ground. The other advantage to he Fluke 771 over a logging oscilliscope is that it eliminates the need to use probes because it is a less invasive clamp on style ammeter.
From what I gathered using a fancy $8K+ electrometer that logs extremely low amounts of stray voltage or current can be a solution. Not sure if the cost-benefit $$$ equation looks good enough though ... plus they & higher end oscilloscopes require probes vs the less invasive clamp on approach.
Any thoughts or am I just consumed by some unproductive wishful thinking for this type of troubleshooting?
