Setting Pass/Fail Thresholds

The following table provides the default, minimum and maximum
thresholds.

Once the thresholds are set, the application will be able to perform
Pass/Fail to determine the status of the various events (pass or fail).

Values that are greater than the predefined fail thresholds are displayed in
white on a red background in the events table.

The Pass/Fail threshold LED, located on the front of the unit, will also
indicate the status (green for pass, red for fail).
