Adjusting the Temperature Offset (Figure 29)

The Temperature Offset is a feature that ensures accurate temperature readings where the food actually cooks, as opposed to where the thermocouple is.

The value entered for temperature offset will deduct from the oven’s temperature reading. For example, if the oven temperature = 500ºF, and the temperature offset is 20ºF, the oven will display 480ºF.

To adjust the Temperature Offset:

1.From Screen 1 of the Test Mode Menu, press the “OFFSET” Soft Key (bottom left).

2.Continue pressing the “OFFSET” Soft Key to adjust the Temperature Offset in 5°F increments.
