This meter will not display raw voltage measurements from the probe per mfgr tech support.

Seems to me I would need to know the meter's calculated calibration slope and offset numbers to be able to adjust for the ATC reading, but I'm probably missing something here, my math is not great...
I guess I could use the method and formulas you provided and do all my readings at 25C. That would work to get more familiar with the readings, but I'm not sure how practical it would be to try and hold all my samples at 25C on brewday.
