As an example, the control is displaying 400°F with the setpoint being 400°F, but the

center of the oven chamber is actually 395°F. This can occur due to oven wall losses

and product loading variations. The operator may change the zone calibration so that

the center of the oven is 400°F when the display re ads 400°F. In this case operate the

oven in manual mode with a setpoint of 400°F. Recor d the center of the chamber (as

measured with an independent sensor). Access the Zone Calibration Page and enter

this measured value as the Zone 2 Actual value, with 400° as the Zone 2 Displayed

value.

Zone 1 can be adjusted using the same method at a lower temperature. The instrument

will then create a linear offset based on the Zone1 and Zone 2 Actual temperature

values. Note that the oven does not have to be heated to adjust the zone parameters if

the zone values are known based on prior experience.
