Figure 9-16 Trend View
The ribbon will display the controls for manipulating the view:
• In the ‘Operating Conditions’ section of the ribbon select any operating Conditions
to add to the graph (optional).
• In the ‘Summary Number’ section of the ribbon, select which Summary Numbers
to add to the graph; one of these is required or the graph will be empty.
Note:
When trending phase changes, be sure that the Phase Quality on the
trended measurements is consistently green; if there are any yellow
or orange icons in the trended measurements, the phase trend will
not be meaningful.

• In the ‘Sensors to View’ section of the ribbon, select which axes to add to the graph;
one of these is required or the graph will be empty.

The measurement list will show all measurements; raw data is not needed to build a
trend.

Once the Summary Number and Sensors to View selection is made the graph is
automatically populated with all measurements that are flagged as ‘Trend’ in the
measurement list; if no measurements are set for ‘Trend’, then no data will be displayed.
Any changes over time in the selected Summary Number and axes will be clear.
