• Changing the Trend Display Time Axis While Recording (Memory
sampling) Is in Progress (Release number 3 or later)
On a DX whose release number is 3 or later, you can change the secondary trend
interval even while recording (memory sampling) is in progress. If you are using the
secondary trend interval to display waveforms and you change it, the time axis will
change immediately afterwards.
Note
Only the displayed time axis changes when you switch to the secondary trend interval. The
data sampling interval does not change.
