the Configure button in the DAQ properties.
In the variable properties, you can select the Is Calculated checkbox and

of the variable. These calculations must be forced to calculate values
using one of the following activities:
• Add a Calculate Variables activity to your test.
• Use the Map Variables window in a data acquisition (DAQ) activity to
build a list of “Additional Variables to Calculate.” These variable values
are recalculated each time the DAQ activity collects data.
The variable editor properties allow you to enter a static default value for
a variable or select Use Previous Test Run Value to set the value. Default Values or
