No matter what you do, short of hand-delivering it if you live close 
enough, the internal battery does not have enough charge to reliably 
ship it, even overnight.  You will need to build or buy a shipping 
container that has an auxiliary battery.  Fluke sells external 
battery packs for $375, or you can make your own.

I have done that experiment a few times.  Mine have always come back 
within one or two tenths of a ppm.  But there is always the chance 
that one won't, so the practice is strongly discouraged once the unit 
is all sorted and calibrated.
