Additional information
Data Quantity and
Memory Capacity
One USB stick with a memory capacity of 1 GB, for example, can record logging data at a
logging interval of 5 minutes for approx. 7 years.
CSV file
CSV files can store only 65535 rows (data records) (up to Microsoft® Excel version 2007,
afterwards there is no limit).
At a logging interval of 5 minutes, the 65535 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 stick. If the logging interval is set longer, this time frame is ex-
tended 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 stick.
After you have backed up the data and removed it from the USB stick, the stick should be
immediately reinserted so that it can record logging data; no further steps are required.

NOTE!
A full USB stick can lead to the loss of data or the overwriting of data.
When inserting the USB stick, make sure that it has a sufficient memory capacity.
