I brought a Digi-cabi DHC-040 2 weeks back, and humidity was stable at 50% where I set. I didn't quite believe as it seems too good to be truth, so I got a digital meter from DIY shop to double check the reading.
The reading stays at 50% on both the meter until I on my air conditioning, the humidity reads between 55%-57% on the second meter I placed in the cabinet, while the cabinet meter still reading 50%. Everything will return to normal about 30minute after I off my aircon. These happened for the pass 3 night.
Anyone encounter similar situation before? Anyone can explain why is this happening? I do however believe that both meter are not faulty because I did see both meter display 70% humidity when measuring outside air.
