Data volume and
storage capacity
A USB flash drive with a storage capacity of 1 GB can record logging data for roughly sev-
en years at a logging interval of five minutes.
CSV file
CSV files can only store 65,535 lines (data records) (up to Microsoft® Excel 2007; there is
no restriction from this version onwards).
At a five-minute logging interval, the 65,535 lines will be written within approximately seven
months (CSV data size of approx. 8 MB).
In order to avoid data loss, the CSV file should be backed up to a PC and deleted from the
USB flash drive within this seven-month period. If the logging interval is set to a longer pe-
riod, this time frame will be increased accordingly.
FLD file
The FLD file should not be larger than 16 MB. This will provide enough storage capacity
for approximately six years at a logging interval of five minutes.
If the file exceeds the 16 MB limit, it should be backed up to a PC and all of the data on the
USB flash drive should be deleted.
After backing up and removing the data, the USB flash drive can be reconnected immedi-
ately to resume recording the logging data without any further steps being required.
Note! Using a full USB flash drive can lead to data loss or data being overwritten. When
using USB flash drives, always ensure that there is sufficient storage capacity on the flash
drive.
NOTE!
Risk of USB flash drive becoming full.
This may result in data being lost or overwritten.
► When using USB flash drives, always ensure that there is sufficient storage capacity
on the flash drive.
