(3) Recording capacity
The recording capacity depends on the capacity of the SD memory card.
One logger fi le is composed of a confi guration fi le and a data fi le.
The data fi le 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 spreadsheet software.
The maximum number of data fi les in a logger is 20 fi les in case of a continuous logger, and
is 550 fi les 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 fi le, the logging will stop.
Recording capacity in case an SD memory card of 256 MB is used with continuous logger
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 fi les, and the capacity of a fi le 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.
