Barometer Trend

Can the barometer trend be made more sensitive? Looking at the graph it’s easy to see it’s falling, but I’m not sure what to set it to register smaller changes. Here’s how mine is set currently:


How about this question then…what do the two settings on the bottom do? I assume they are for barometer and dewpoint…

I would like to make my barometer state the current trend, either rising or falling, instead of the seemly constant steady indicator. Apparently as it is set now it takes a major change in the barometer before it will show a rising/falling indication…

set the fine tune (the dp means decimal place, not dew point) to say 0.5 and the one that is 1.0 now to zero
