Just bought a digital dry cabinet 1+ weeks ago (almost 2 weeks).
Set it up to 45RH, and leave it on 24/7.
Strangely, it is up and down between 45 and 46. Never stays on 45. And I opened only once in those week. Is this normal? I thought it only needs 3 days and it will go to 45, stays there until we open the cab which wet air comes into the cab.
