3. Positive overflow/negative overflow: *
If more than one faulty data item occurs at the same time, the DR recorder prints them while

Notes on daylight savings time
When the function to shift the time scale between standard time and daylight savings time is
specified, the report for the day to shift from standard time to the daylight savings time seemingly
includes data for only a 23-hour day and, at the same time, the report for the day to shift daylight
savings time to standard time seemingly includes the data for a 25 hour day.
If you specify the time to make a report at the same time as the shift from standard time to
daylight savings time, or vice versa, the report will be generated based on the time scale after the
shift.
