7.7.3 Data records
If several data records are loaded in the data logger at the same time, the data record to be displayed
has to be selected via the Data record list field. There are three types of data records:
Online data record
The online data record is the only data record which serves to establish a connection to the target
system. When the online data record has established the connection completely, it can
communicate with the target system.
• In the Data record list field, the online data record is marked with a prefixed asterisk (*).
Offline data record
The offline data record is a data record already stored in the project and loaded in the data logger
again, or a data record imported from a file.
Merge data record
The merge data record is automatically available in the Data record list field if two or more data
records are loaded in the data logger at the same time.
• In the merge data record, several characteristics from the currently loaded data records can be
overlaid, e.g. to compare signal characteristics from different recordings.  Overlay function
