man I like that link btw! I've been doing color codes and tolerance by hand gah! lol

I'm thinking the same, After all, I got this box of brand new 2% resistors, and I DO measure them before I put them in.
I have 2 new digital meters, ( cheap ) I only got the 2nd one because the 1st did not have autorange and only went up as high as 20m, new one goes up to 200m.
Checking a removed resistor measures almost the same on both meters, ( less than 1-2% difference )
Also, when I take the removed resistors (after I replace them ) to work an tested with the high $$$ fluke, which is required to get calibrated every year, I get virtually the same results.
So, given that the set is over 50 years old, and that most resistors are of 10% or 20% how critical of an eye should on on for checking them to be on target?
