Hello,
when I have a "accident" from my unbuffered LTZ-references by shorting
the output (for a very short time),
(so setting the temperature setpoint to infinite and thus the heater
cirquit goes to maximum output)
I usually have a large shift on the device. (several ppms).
A part of the shift can be cured by power cycling (cooling down and
heating up to normal operating temperature).
The remaining shift (-2 .. -5 ppm usually) is permanently on the device.
After such a event I usually have around 6 months increased ageing rate
until it goes back to the normal -1 .. -2ppm/a
with best regards
Andreas

Does anyone know if desoldering one and resoldering resets the aging

I don't think it "resets" as such, but it certainly starts some kind
of aging process, as does hard knocks, thermal shocks, vibration, ...
