Data Amount and One USB thumb drive with a memory capacity of 1 GB, for example, can record logging
Memory Capacity data at a logging interval of 5 minutes for approx. 7 years.
CSV file
CSV files can store only 65,535 rows (data records) (up to Microsoft® Excel version 2007,
afterwards there is no limit).
At a logging interval of 5 minutes, the 65,535 rows are written within approx. 7 months
(CSV data size of approx. 8 MB).
To avoid a loss of data, the CSV file should be backed up to a PC within these 7 months
and deleted from the USB thumb drive. If the logging interval is set longer, this time frame
is extended accordingly.
FLD file
The FLD file should not be larger than 16 MB. At a logging interval of 5 minutes, this cor-
responds to a storage duration of approx. 6 years.
If the file exceeds this 16 MB limit, it should be backed up to a PC, and all data should be
deleted from the USB thumb drive.
After you have backed up the data and removed it from the USB thumb drive, the thumb
drive should be immediately reinserted so that it can record logging data; no further steps
are required.
Notice! A full USB thumb drive can lead to loss of data or overwriting of data. When insert-
ing the USB thumb drive, make sure that it has a sufficient memory capacity.
Risk from a full USB thumb drive.
This can result in the loss of data or data being overwritten.
► When inserting the USB thumb drive, make sure that it has a sufficient memory capac-
