!= | Selects all data that contains values not equal to the value in T race Value 1.
< | Selects all data less than the value in T race Value 1.
> | Selects all data greater than the value in T race Value 1. Alpha characters use the order of the alphabet
<= | Selects all data that is less than or equal to the value in Trace Value 1. Alpha characters use the order of the alphabet.
>= | Selects all data that is greater than or equal to the value in Tr ace Value 1. Alpha characters use the order of the alphabet.
CONTAINS | Selects all data that contains any part of the value in the T race Value 1.
BETWEEN | Selects all data that matches and falls between the values in Trace Value 1 and Trace Value 2. Alpha characters use the order of the alphabet.
SORT ASC. | Selects all data containing trace values for the item selected in Trace Name and sorts it from ascending (lowest to highest). Alpha trace values are sorted according to the order of the alphabet.
SORT DESC. | Selects all data containing trace values for the item selected in Trace Name and sorts it descending (highest to lowest). Alpha trace values are sorted according to the order of the alphabet.
