Trend Display
Explanation
Set the time axis in terms of T/div (time per grid).
Set the time per division in the range of 3 s to 1 day.
The data update interval of the trend is determined by the data update rate and the time
axis (T/div). For example, if the data update rate and T/div are set to 50 ms and 3 s/div,
respectively, the trend display is updated every second. If the data update rate and T/div
are set to 10 s and 3 s/div, respectively, the trend display is updated every 10 s and the
trend data is shown as a line graph at 10-s intervals. If T/div is set to 1 day, the data
update interval of the trend is 1728 s regardless of the data update rate setting.
Note
• If the time axis is changed, the retrieval of trend waveform data restarts. The trend display up
to that point is cleared and the trend starts from the right end.
• One division on the trend display corresponds to 50 rasters. For example, if T/div is set to 1
day, 1 raster is equal to 1728 s (= 1 day/50). In this case, the data update interval of the trend
is 1728 s, and the data is displayed P-P compressed. For a description of rasters and P-P
compression, see section 2.7.
