Interpret the data quality indicators

The data quality indicators are symbols that appear on a number of summary displays. They are located on the window frame to the right of the line they are associated with. These icons indicate the condition of points on the display. The indicators are described in the following sections in order of priority.

Note: If a point is tagged with more than one quality condition, only the highest priority indicator appears on the display (where 1 is the highest priority).

There are two priority levels:

• Level 1: Manual Override

• Level 2: Error

Trend pen trace data quality indicator colors are as follows:

• Green: Normal (Pen Trace Color)

• Pink: Manual Override

• Blue: Offscan/Offline

• Red: Alarm

• Yellow: Unknown

  Name	Icon	Priority Level	Description
  Manual Override		1	This indicator appears at the right side of a line of data to show that you have placed the point into manual override mode and has possibly entered a value to override the point’s normal data source. You can manually override telemetry or calculated points to prevent the overridden points from being updated via telemetry or calculation. Note: The manual override indicator is never displayed opposite manual points. These points are always in the manual mode and cannot be overridden.
  Error		2	When this indicator appears for telemetry points, it indicates that the value has exceeded instrument limits. When this symbol appears against a calculated point, it indicates either the occurrence of an Application Calculation Engine (ACE) error, such as divide-by-zero, or that an application has declared the value to be suspect or erroneous.
