Data Archive

When you dump data on a PC using the endless loop memory function, the most recent data are
queued to those already existing in the PC memory and they represent a single group of measurement
consecutive sessions: this group of measurements appearing in the Report List is called "Dynamic
Report File" and is indicated by the DRF abbreviation. For instance, a group might be composed of
the seven daily measurements detected in a museum in a week time. When this block of measure-
ments has been completed, the group of data can be conveniently stored: in this way, it will not ap-
pear anymore in the Report List every time a new dump is made. All data stored on a PC can be re-
called to be viewed and, if needed, they can be deleted.
Data dumped during an endless loop memory session, are reorganized by groups using the Sort Data
command : every group of data will be composed of measurements detected at the same time, on the
same day, in the same week, month or year, or according to the download data.
