Data tab—Results Summary view

The

Results Summary

view displays the test results summarized in a grid or spreadsheet

form. Each column represents one test result.

Figure 48.

Data

tab—

Results Summary

view example.

The first two rows are used as the heading for each column, displaying the date and time the

test was performed. If all tests that were performed passed, the background of the date/time

cell will be green. If one or more tests fail, the background will be red. If no tests were

performed, the cell background will be gray.
Use the scroll bars to the right and bottom to scroll through the results for each test category.

The side-by-side view allows all test results for a motor to be seen in one view, facilitating

comparison.
To print a copy of this view, click the right mouse button anywhere on the grid. A dialog box

will appear allowing you to choose a printer and parameters for printing the grid.
