Mix 1 tablespoon of salt with just enough DW to make a paste.
Put this in a small container like a bottlecap
Put the bottlecap and your hygrometer in a ziplock style baggie with enogh free stadning air that neither touch the other
Now doublebag the whole thing
wait EIGHT hours
doun't cheat at 4, really wait 8
The exact humidity in the bag is now 75%
adjust your hygrometer accordingly
double check if necessary (yeah, wait 8 hours again)
you'll now have a calibrated hygrometer
hope this helps,
