(3) Recording capacity
The recording capacity depends on the capacity of the SD memory card.
One logger file is composed of a configuration file and a data file.
The data file is stored as divided by 65,500 lines for permitting high-speed access and due to
restrictions in the maximum number of lines of CSV display of Microsoft Excel.
The maximum number of data files in a logger is 20 files in case of a continuous logger, and
is 550 files in case of an appointed time logger. If the capacity becomes short during logging
operation, logging operation terminates with the following screen displayed.
Replace the SD memory card immediately, if this screen is displayed.
Press the
ESC
key, or remove the memory card, the message will be cleared.
Note) After reaching the maximum data file, the logging will stop.
Recording capacity in case an SD memory card of 256 MB is used with continuous logger
In case where the preservation period is 30 seconds and where logger data of all of 14 types is
stored, it is possible to store measured data for about a year.
In the case stated above, the measured data is divided into 16 files, and the capacity of a file is
about 15 MB.
See “10.2.1 Setting of data logger function” for the continuous logger and appointed time logger.
See “16.5.1 Types of measured data to be logged” for logger data types.
