How to Calibrate a Hygrometer?

I'm doing my second hygrometer using the salt test. This one just, as the other was at 75% within an hour. The dial hasn't moved in 3 hours. On the other, I waited 24 hours and the dial was solid the entire time. Other sites I've read recommend 12 hour wait. So far, I haven't seen the need to wait that long. Each time the meter started at an RH in 30's.

I just started the calibration on my hygrometer last night. After about 12 hours it is sitting at 78%. The salt calibration method is really simple and easy to do. I have the container sitting on top of the humidor where the humidor will be kept to try and keep the conditions as ambient as possible.
