Repeatability Checking
Use this menu to check repeatability. To perform this check, the test results to be compared
with each other must have been obtained from tests executed under the same conditions with
the same test system. Select one of the past test result files that has the same test conditions
as the current one.
Values are compared for each harmonic order conforming to the selected test standard as a
test condition and then the values are automatically judged. This menu can be set after
analysis and test execution. Before the test, the menu is displayed dimmed and cannot be
selected.

Select a past test result file in the File Operation display. File operations such as file name
change and file deletion are possible.
