Observations. - During temperature ramp-up, CH1 and CH2 generally show higher readings than the Internal Sensor. - A larger deviation between CH2 and CH1 is observed during ramp-up phase (500°F to 650°F) — up to 33°F.

Conclusion
We need to collect data on the time it takes for the temperature to rise
from 75°F to 750°F. Based on current datapoints, the temperature rise
from 77°F to 700°F is estimated to take approximately 17 minutes (10.0 +
5.0 + 2.0 minutes).
