Masking
automated function where results above or below a specified threshold are reported with a defined result. For example, the instrument may report “ethanol below administrative threshold” or “0.000 g/210 L ethanol” for a response below 0.005 g/210 L. Another example may be reporting “Results greater than 0.400 g/210 L” or “Over Range” for a response above 0.400 g/210 L.
