I use a more accurate K Type Thermocouple probe. I put 6 of them on with Capton tape. This will give you an accurate temp map of the plates. Change the set point from 175f - 225f. take notes what the real temps are at those set points. You can just affix the heat offset chart to the press. You wont ever need to redo this unless u change the heaters or plates.
