Historical Trend Display (Figure 4.8)
The EchoSmart Controller captures and stores the current measurement value every
six minutes. The database is updated on a “first in/first out” basis to maintain a
continuous register of the most recent seven days of data for all sensors. Newest
data is reported on the right side of the screen.
The Historical Trend Display provides a graphical illustration of stored
measurements for the selected sensor. The user may choose to view from one to
seven days of data.
