Expanding the Trend Display
You may expand the trend display to include only an hour’s worth of information.
With EXPAND ON, the TIME BASE key does not operate and updating of the
trend graph is suspended on the graph as it is currently displayed. When
EXPAND is OFF, the trend graph returns to its original display. Moving the cursor
while EXPAND is ON does not change the cursor’s position in the OFF mode.
Tabular Trends Features
Setting a Time Interval
You can display acquired data at various time intervals: 1-, 5-, 10-, 15-, and
30-minutes; and 1-, 1.5-, and 3-hours.
For continuous data, the value displayed in the tabular trend table is the value
taken at the displayed time. It is not an average of all readings taken during that
time period.
When more than one episodic reading occurs in the same time interval, only the
most recent value is displayed. Asterisks to the right of the episodic value
indicates that more data entries are available for that time interval.
The trend table automatically updates at the end of each time interval. This shifts
all data columns to the left to include the new interval.
Viewing Off-Screen Information
You can view up to 22 rows and 7 columns of parameter data on a single screen
in a tabular trend.
You can view additional parameters by moving rows up or down. When you select
PAGE, the arrow keys move the entire page up or down. When you select
SCROLL, the arrow keys move the display up or down one parameter row at a
time.
You can view data collected at other times by moving columns left or right. When
you select PAGE, the arrow keys move the display to show an entirely new set of
columns. When you select SCROLL, the arrow keys move the display left or right
by one column.
