1.8.4 Improper Controller Function
Sensitivity or "Stretch Time." Sensitivity—or stretch time—is a programmable feature that
increases the cook time countdown based on variations in the oil temperature from the
setpoint (e.g., when cold product is dropped into the oil, causing the oil temperature to drop).
The sensitivity for each product button has 10 settings (0 through 9). A "0" sensitivity setting
will disable the feature (no change in cooking time), while a nine will provide the highest
sensitivity or the most change. The correct sensitivity for any product is based on the product
type, its density, the setpoint temperature, and the customer's own requirements.
