Default Re: How to Calibrate a Hygrometer?

Just curious, what is the importance of having the salt dampened and not saturated? Does it affect the RH? For instance, if the salt is saturated with water, will it not produce the ideal 75% RH?

And how specific is this? Are we talking a big difference between the two?
