Looking at the Graphical Plot (TrendPlot™)
The test tool continuously logs the maximum, average, and
minimum readings, and displays all values as a graph, as
shown in Figure 4-3. Vertical scaling and horizontal time
compression are automatically resized to fit the TrendPlot
on the display. The TrendPlot is slowly traced on the
display from left to right until the screen is written and the
time scale is resized. The initial time scale is 15s/DIV; after
a full screen the scale is compressed to 30s, 1 min, 2 min,
etc., to a maximum of 40 days over a whole display.
ATTENTION
An overload of MAX or MIN will stop the Min Max
record mode. The overloaded value (Min or Max) and
the AVG are then displayed in reverse video, and the
time stamp of the overloaded value is stopped. The
TrendPlot will continue.
