The title should read just bought dhc80. Was sleepy when I posted. Temp is stable at 29 degrees. I want humidity at 50%, but it keeps hovering at 42-43%.
You want RH=50%, Did you pre-set the RH to 50%?
FYI: The factory pre-set is set at 45% RH or ba ba..
I suspect that you did not make any change to the pre-set of the RH. Thus, your pre-set is still set to 45% and it keeps hovering at 42-43% which is within the specification.
==========================================
For Digicabi's DHC professional series, is a digital display(temperature and RH %) with Digital Humidity Controlled system[Pre-set RH value].
Base on the specification, For DHC Series, you can control the humidity using the LCD Hygrometer on the front panel. There is a set button which you can set the humidity level you desire and the system will work according to the settings. You are able to set precise humidity for this series.(+/- 2%)
FYI: The factory pre-set is set at 45% RH. [i.e. 47% to 43% ] or {48% to 42% worst case}
You Paid higher price for the better humidity control (Digital).
So if you pre-set the RH to 50% (Digital Humidity controlled system), when the dry cabinet is stablised condition: RH % value(stable) shall falls within +/- 2%
; i.e. 52% to 48%.
For me I will take 53% to 47% to consider the control device is working. Look for the agent/Manfu .... "Lemon" product ??? Ha Ha Ha

Some brand or model is a digital display(temperature and RH %) but Analog Humidity Controlled system[Manual adjust the set RH value by turning knob-Agar Agar ].
