It finally dawn on me, but when you put a .9°F offset for the 75 (due to up to date transmitter & old sensor) it makes the DP go up 1°. To get an actual DP report from the 75, I did a -2% offset. But it’s strange that the console doesn’t adjust RH when you do a temperature calibration.

I guess it’s better to be slow than never. Lol

On a off topic note, the new Davis one spoon tipper is worth the investment to get and replace your old tipping spoons!

That's because the humidity is a straight out measurement, just like the temp. If you change the temp., the dew point is recalculated to reflect the humidity measured. That's also why there's an offset offered for both temp and humidity, but not the dew point.
