9.5.1 Mode of operation
All recordable faults are documented in the log book and stored in a continuously updated ring memory. Depending on the
volume, the faults are stored for at least three months and then overwritten. The data can be exported and evaluated (*txt for-
mat). The data in the memory cannot be deleted. For a better overview, the day on which a fault occurred is underlined in the
date selection. Once this day has been selected, the temperature display or the event display can be accessed.
The temperature data (optional) is also recorded. The ring memory can last for two years with a 15-minute recording interval.
After two years, the oldest data records in the ring memory are overwritten. The logged data can be directly output onto the
display or read via a data carrier. The data (* .txt format) can be imported into a spreadsheet and evaluated. The data in the
memory cannot be deleted.
9.5.2 Licence
release
If the data logger is retrospectively ordered, the display number must be reported to the factory. The display number can be
found under Settings, Control panel, Licence. This display number is allocated to a release number in the factory, which is ente-
red under the display number. Once the release number has been entered in the display, the temperature data is recorded.
