■Considerations
• The saving period must be set to a length sufficient to sample, receive, and accumulate changed data.
• If a file saving trigger is satisfied between when a recording startup trigger is satisfied and when a specified period elapses,
data for the specified period is saved to a save destination specified in the recording setting when it is accumulated.
