"PYROM" key will automatically transfer 12 temps from an integrated pyrometer.

Otherwise...
The keypad allows you to manually input a set of temperatures for analysis.
As you enter the 9 digits for each corner, they appear above the keypad.
When you finish each corner, tap the key for that corner, and it will record.

"DONE" key will start the analysis and recommendations,
after all 12 temperatures are correct.
