(3) Conditions for auto logging completion
When one of the following conditions is met, the auto logging is terminated. The following conditions can be set in
combination. In that case, the auto logging is terminated when either of the conditions is met first.
Condition
Data logging stop
Timer
(a) When "Data logging stop" is set
The auto logging is terminated when all or any of the configured data loggings is stopped.
Data logging stop is defined as follows:
• Continuous logging: The number of saved files in the Save setting is exceeded, and data logging is
completed.
• Trigger logging: Data of the specified number of records have been collected and written to the SD
memory card, and data logging is completed.
• Specification period logging: The number of saved files in the Save setting is exceeded, and data logging
is completed.
• Data logging is stopped from the configuration tool.
● When continuous logging or specification period logging is selected for a data logging for which auto logging is enabled,
if "Overwrite" is selected in the "Number of saved files" setting, the data logging will not be terminated. Therefore, select
"Stop".
● If "When any of the data loggings stops" is selected, operation of a data logging in execution, which is other than the
stopped one, is the same as the operation performed after the time specified with the timer has elapsed.
(b) When "Timer" is set
After start of data logging execution, when operating time reaches the specified time, all of the data collected
until then are saved on the SD memory card, and the auto logging is completed. However, for trigger logging, if
data of the specified number of records have not been collected yet, the data including collected data will not
be saved.
If a data logging is temporarily stopped before completion of auto logging and then restarted, the timer is cleared to zero.
However, when a temporary stop is caused by turning off the special relay (Data logging start), the timer continues running
even while the data logging is temporarily stopped.
Select one from the following.
• When all data loggings stop
• When any of the data loggings stops
Select "Complete with timer".
Setting range for "Elapsed time": 1 to 86400 seconds (in increments of 1s)
