If error occurs, just click “DataLogger icon” again.After the data was downloaded, the left hand side will show how many data sets were loaded and detail information for each data set (start data, start time, recording rate and record numbers).

For Example:

It will transfer first data set to graph on the right hand side. The user can also click at any other data set to choose that set for graph.

Graph:

Toolbar:

– Display or hide Statistic1.
– Display or hide Statistic2.
– Normal cursor.
– When selected, the mouse cursor will become a cross sign when moving to the graph, click on the graph to mark a cross sign on the graph. This is available only when “Split” option is unchecked. And all the mark you make will exist with T1.
– When selected, the mouse cursor will become an “I” sign when moving to the graph, click on the graph to annotate. This is available only when “Split” option is unchecked. And all the text you make will exist with T1.
-Separate the four channel.
-Combine the four channel.
– Graph Customization
– Change the Y axis extension.Note: When the Split is unchecked, graph will use T1 as the Y axis display range.
