Edgetech DewPrime II Hygrometer

[Pete2]

Hello!

I recently acquired this very interesting test instrument: Edgetech DewPrime II chilled mirror hygrometer. You can find them on ebay for a couple of hundred dollars depending on condition. My unit seems to work or at least it powers on but I have no idea how to operate it since I can't find the manual for it and the menu system is not very clear since it uses 7-seg LED display for everything.

I have contacted Edgetech several times and initially got an answer asking for the serial number but after that nothing. So I'm writing here to ask if someone has the manual for it or can tell me how the menu and settings work so I can test if it really works. Edgetech told me that the manual is specific to the model configuration but I think I can manage with any manual for the DewPrime II (or even DewPrime I). I can find a manual for the Dew Master but that's a completely different unit.
