1.8.4 Improper Computer 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.
