Trend rate switching
Set this to On to enable the function that switches the trend interval while the recording is in
progress.
During data acquisition, you can switch from the normal trend interval to the secondary trend
interval. You can also switch back to the normal trend interval.
Note
Only the displayed time axis changes when you switch to the secondary trend interval. The trend
interval of recording data does not change.
Second interval [/div]
Set the time per division for the secondary interval. You cannot choose a secondary interval
that is shorter than the scan interval.
