Next time turn ON the aircon for one hour before you open the door of your dry cabinet; it'll behave like normal.
shouldn't be shot up right if the cabinet door is always close

Refer post #3, the level shot up After TS opened the door and put something in it.
Anyway, a short period of high humility is not going to result in something drastic to the equipments.. After all, when the equipment is being used, it is exposed to high humility for even much longer periods, what is a rise of 10% in humility for a few minutes or hours?

Regardless 1 sec or 3sec, the RH will still shoot up because once you open the door, the room air is push into the cabinet (open door creates suction just like fridge).
Why does it take much longer time to reduce RH after prolong opening has these main reasons.
- You equipment begin to absorb moisture.
- Don't forget, your breath is 80% moist.
- When you rearrange the item, you transfer moisture to the item.
And why opening and close door "without" touching any item will down the RH faster momentarly than above situation is bec moisture in the cabinet is absorbed by dryer surface of equipment.
Which is why fan power within the cabinet will speed thing up by a lot. Of course silica gel with fan is the ultimate.

The rise is insignificant anyway.
same thing happens to my dry cabinet. I have been monitoring it for a week.. RH shot up to 48% almost every morning [the red light inside automatically switched on], and normally, RH will be back to normal at 40% in the afternoon. I didn't opened the door, and don't understand how the dry cabinet works... I am using Akarui Digi. Is this a norm?
Yep...Yesterday my dry cabinet reading rose from 43% to 48%...Probably because of high humidity when I opened the door for a couple of seconds.
