A bit of a silly video IMHO. I can't take anyone seriously who measures the noise on a 6.5 digit multimeter by looking at the digits which change as it is across his standard bench power supply. Personally I would have thought one measured the stability of the bench supply by measuring with the DVM rather than the other way around > On the 3458A that I was able to 'kill' the 'cal RAM', the 'cal counter' was > at '1' when I received it.

I was thinking about that cal ram, and the issues changing the battery. If one intends sending the meter away for cal, is there any point in worrying about if the ram is kept alive? I guess it might be nice to know the performance before it was calibrated as Agilent will give you, but there is a bit of a risk of damaging chaning the battery live. I intend changing the battery in mine then sending it for cal.
