sampling timing occur within one scan, only one sampling is performed in the END processing.
(b) Samples data at the specified time interval
*1
Select this when data are to be collected at relatively short intervals and in real time.
When 5 milliseconds are specified
*1 Even if clock data are changed during execution of data logging, actual sampling interval will not be changed.
