There is a principle here that I can't see mentioned and that is how easy it is to discard something as a cause of a problem because it seems so minor, so routine (i.e. removing the "spare" multimeter) and therefore getting blinkered on what is going on.
There are more than a few times where I am scratching my head as to "how could my change have possibly broken this" only to remember a couple of hours later that I had made another change somewhere, or rebooted, or changed a config file temporarily.
I guess it just says that we all need to log everything we do, including removing spare multi-meters, so that by looking over the list we can remember these things.
