Trends

The monitored parameters described in the previous section are trended as one minute averaged values over a running
24-hour period. Trend data is accessed by pressing the screen button on the membrane panel to the left of the touch
screen or by pressing the screen indicator in the top center portion of the touch screen display. The screen menu will
appear. Press the TREND button on the screen menu to open the trends screen.

Note:
If left open the Trends Window will update every 10 minutes.
Four histograms and a spreadsheet are displayed on the touch screen. Each histogram and column on the spreadsheet
can be configured from the list of monitored parameters as well as events. Touch the title bar of any histogram or the
heading of any column to open a scrollable menu. Move through the list by turning the data dial. Highlight the item to be
displayed and press the highlighted display or the ACCEPT button above the data dial to accept the new item for display.
Histograms can be scaled by touching either axis. With the axis highlighted, use the data dial to adjust the scale. Touch
the axis again or press the ACCEPT button to accept the change.
To look at histogram or spreadsheet trends over time, press the FREEZE button and use the data dial to move the
cursor through the time line. The time line is shown as yellow text on the spreadsheet. Event markers appear in green
text.
Note:
Changing the date / time back on the instrument's internal clock erases stored trend data.
