It's the variability of the source that drives you nuts.

You are spot on, if the source is varying, even slightly, with the higher resolution meter, the more the least significant digits are going to keep altering in an effort to reflect the changing input. Whereas with fewer digits, that change has got to be much bigger in order to alter the least significant digit. 3.5 meter, no change in display, 4.5 meter sometimes the last digit will go up or down by 1, 5.5 meter, last 2 digits were changing all the time on the power supply. Its like a proverb, man with 3.5 and 4.5 digits, knows the voltage, man with 5.5 or more digits is unsure of the voltage due to last digits changing. :-DD

Quite frankly the 5.5 digits is overkill for me. I could get along fine with 4.5 or even 3.5 digits. But it's nice to have....just in case.
6.5 digits? Only if drops from heaven for free. :-DD

TEA Proverb #382: Man with more digits knows when he needs to buy a more stable power source (or replace the filter caps). :-DD

Or get rid of PWM-regulated lighting. :palm:
In other news...
It's evolving. :-DD

Can we make test equipment do that?
Alice: "Hey, how come your 34401A has one more digit than mine? "
Bob: "It just evolved last night."
Alice: "How'd it do that?"
Bob: "I'm not sure. I did leave it monitoring the output of my 1kV power supply for a while yesterday."
Berni:
As long as said test gear doesn't 'evolve' in the form of suddenly saying on boot up:
"Selftest Clock board: FAIL (222)"

Oh dear.
I think I'll have to get an 8800A, just so I can fondle those switches.
I really wish people wouldn't post geekporn pictures.

Shhh, don't say stuff like that. It increases the probability of the opposite occurring.
