Plotting Measurements Over Time
(TrendPlot™)
Use the TrendPlot function to plot a graph of Scope or
Meter measurements (readings) as function of time.
Starting a TrendPlot Function
To start a TrendPlot, do the following:
1 Make automatic Scope or Meter measurements,
see Chapter 1. The readings will be plotted!
2
RECORDER
Open the RECORDER main menu.
3 Highlight Trend Plot.
4
ENTER
Start the TrendPlot recording.
The test tool continuously records the digital readings of
the measurements and displays these as a graph. The
TrendPlot graph rolls from right to left like a paper chart
recorder.
Observe that the recorded time from start appears at the
bottom of the screen. The present reading appears on top
of the screen. (See Figure 15.)
Note
When simultaneously TrendPlotting two readings,
the screen area is split into two sections of four
divisions each. When simultaneously
TrendPlotting three or four readings, the screen
area is split into three or four sections of two
divisions each.
Figure 15. TrendPlot Reading
When the test tool is in automatic mode, automatic vertical
scaling is used to fit the TrendPlot graph on the screen.
