Figure 17. TrendPlot Reading
When the test tool is in automatic mode, automatic vertical scaling is used to fit the TrendPlot
graph on the screen.
Note
Scope TrendPlot is not possible on cursor related measurements. As an alternative you
may use the PC software FlukeView™ ScopeMeter™.
Recorded Data Display
When in normal view (NORMAL), only the twelve most recently recorded divisions are displayed
on screen. All previous recordings are stored in memory.

When the recorder memory is full, an automatic compression algorithm is used to compress all
samples into half of the memory without loss of transients. The other half of the recorder memory
is free again to continue recording.

represent either the start time of the recording (Time of Day) or the time elapsed since the start of
the recording (From Start).
To change the time reference:
1. Press
2
to open the RECORDER OPTIONS menu.
2. Use the cursor and

or
