Term

THRESHOLD TEMP.

Definition

Calibration
Thetuning of an instrument according to a standard value. Calibrationon a Smart Tag is the temperature at which is performs tospecification most optimally.
Cumulative Temperature
The total amount of time by QC code that the Smart Tag has been exposed to temperatures above the threshold.
Excursion
Deviation from a specified limit. For the Smart Tag - when the cumulative temperature exceeds the threshold temperature for a specific time period.
StopTemperature
The temperature that must be reached to discontinue the cumulative time over a threshold temperature.
Threshold Temperature
The temperature level that must be maintained for a specific product category. Smart Tags are programmed to measure for this temperature.
