I meant to say, maybe an Agilent meter would not have the reliability
problems of an older HP, but be more stable than a new Keysight.
Does anyone know how old the units have to be to reach maximum stability?
Is it the LTZ1000A reference that improves with age, or the ADC? I assume
the zener reference, but I don't know.
