"Preconditions" Category
Depending on the connected instrumentation, thousands of Preconditions variables exist. They allow you to display the device settings before a sample run in the Audit Trails. (For more information about Audit Trails, refer to Data Management Audit Trails.) The Preconditions are displayed if you selected Preconditions only or Preconditions and Run on the View or context menu.
The list below contains some of the variables that are typically available during data acquisition with a P680 pump or a UVD 340 detector.
