* When the CSV le format is set after ring and relay function is enabled, the sampling in parentheses
() cannot be selected.
•
When the internal RAM is selected and the external sampling is set, the data is read in 1 μs as internal
processing, an external pulse is used, and the next internal processing data is write to the memory.
Therefore, the capturing interval is at maximum 1 μs and the maximum input error is 1 μs.
Please use the external sampling function within the range where this error is not a problem.

•
When the external sampling function is set to On and then internal memory/SD card/USB memory is
selected, the internal processing interval is 1 ms. The capturing interval is also 1 ms maximum.
•
If the external sampling function is ON, the external input cannot be selected for the trigger setting.
If the external input has already been set, the trigger will be set to Off.
