Help with humidity

[HelpingHand]

hello,

I’m posting this for my neighbour who has just got started with incubating eggs

He has bought a 48 egg incubator and set it all up , but the humidity gauge is resolutely set at 68 degrees

We’ve followed the instructions to set humidity, and tried changing humidity in the room , but it’s not worked

Can anyone suggest how we might reduce the humidity, or perhaps explain how these units regulate the humidity?

Or is it likely it’s faulty? ( its 30 days old )

I will try and post a picture of the unit.

Use a different hygrometer, or do a search on how to measure relative humidity via wet bulb.
