Dry Cabi


There should be a nob at the back which allows you to adjust.I believe you want to increase the humidity? turn it anti-clockwise.
 

Every dry cabinet comes with an operation manual. It describes the typical RH levels for different types of items and also how to achieve this.
 

set the control dial to 1 o'clock or 2 o'clock position.
And then once the RH settles, fine tune.

This worked for me after reading previous posts.
 

Wenxi, i hope you don't get flamed for this because i recall this has been ask many times. a search using the function above will tell.

Just turn the knob to between 12 - 2pm, and let it settle and see what you get. From there adjust accordingly. I suppose when you started this thread, you already know what's the RH you need to achieve?

Anyway, i'm 4 days late, but here's wishing you a belated happy birthday. =)
