Calibrating digital hygrometer
I know there are a million threads about humidity and calibrating hygrometers but I have to ask anyways. I have a Xikar digital hygro that I calibrated using the salt in a cap method. Anywhere I put the hygro with a humidity device...a water pillow, cigar.com humi-can, or Xikar 100ct humidification puck, it reads 90%. I'm using Xikar's glycol solution and I'm not cutting it with distilled water. So if I have the Xikar puck in a zip lock back with the hygrometer, would I have to leave it there for hours like with the salt cap? Or can I assume in a small ziplock back the puck is creating a 70% RH enviroment quickly? What do you guys think? I'll probably just take it to the shop tomorrow and calibrate it in their walk in humidor.

From what I've read, analogs generally need to be salt-tested once a month or so to remain accurate; digital's should be salt-tested once or twice a year to make sure they stay accurate.
Like Lasabar already said, you either use salt to calibrate, or a boveda pack - not both, and certainly never use the humidifying puck to calibrate - it should be the hygro and the salt/boveda pack in a clear ziplock back - nothing else.
4 hours is what the instructions that come with it say to do. I let mine sit a second time for 12-16 hours and it was 75% exactly for a long time. I think it's working fine now since its reading 73/77 in my humidor right now and pretty much stays at that. The newer Xikar digitals have 2 buttons now instead of the green diamond button. One changes between C to F and the other calibrates the RH.
