4.6.1 View Data
This function allows the user to review all the data that is stored
in the non-volatile data memory.
Data is stored in groups, or “events”. An event is created and
stored when the unit is turned on, or when any configuration
parameter is changed (in program mode). When an event is
created, all vital configuration parameters are stored. Each
event can contain many “data” points. A data point consists of;
the sample number, time (hour : minute), tube ID, and
measurement value.
