oh ok so i didnt run the test for long enough?
thats actually comforting knowing i might've messed up rather then the thought that all my logged readings have been 12 % off for the last 8 months...yikes.
ok so i'll re-do the test tonight...
will 12 hrs be sufficient? if the humidity gets over 90% the accurite will read it as "HI" & then i wont know exactly what it is at that point...so...
does the salt in the soda cap only create 75% humidity even after 24 hrs?
