Hi, first post! Yeah, I ran into this issue a while back. Fortunately for most applications 10mV resolution is fine (eg measuring charge state on Li-ion cells) but I did find that old meters do seem to experience random drift failures of precision resistors and more so trimpots. Would it be a

>>> My 732A e.g. has a drift of only about 0.2ppm >>> pa over a couple of year Hope you don't mind me jumping on this thread and asking a basic question: is there any kind of procedure for the 'enthusiast' (say with single 3458A/single 732 and not say 4x732) to measure the drift of a

Igor, I would actually ignore the 1V and 1.018V outputs. You can always determine their actual value using your 3458A in transfer mode against the 10V. The purpose of a voltage reference is not to be at exactly the nominal value all the time (requiring readjustment), but just to be close to
