A threshold range defines the boundaries of multiple limits for acceptable ranges for data. When the field value falls outside the valid range, the value is considered to be out-of-threshold range. You can set up out-of-range levels, such as warning and danger levels.
Note: The Data Type of a threshold range item on a Quality field is defined as a Numeric data type and matches the data type of the parent field.
How it looks in the data grid
The threshold colors display in the Production Analyst results grid to inform operators of out-of-range data.

Example
In this example, the specification is temperature and ideal temperature is between 7°C and 9°C.
