E1 Summary results
The E1 Summary result category displays a large “All Summary Results OK”
message if no anomalies or defects have been detected. If anomalies are
detected, results are displayed.
Error results, key results that are out-of-specification, or key informational
results are displayed. This allows quick access to the results without having to
search each category.
Table 9 describes the results that appear in the E1 Summary category.
