hi Niko…how have you been?
as far as I know and thought the first 2 numbers after the first letter on the logger are the year of manufacture…so I think it is 2017, 1st month 10th day…so january 10, 2017…from the MFG CODE of E170110
at least that is what it says here… https://www.manula.com/manuals/pws/davis-kb/1/en/topic/find-the-model-mfg-code
