Using the User Markers

View Menu > Graph View > Set as Start, End Markers > Using the User Markers

The user markers are events recorded in the logger data record by the pressing of the button on the front of the logger.  These events are logged along with the temperature data, and each event takes up the equivalent space of one logged sample.

When the graph is displayed, samples with user markers attached are displayed with the flag symbol.

You can use these markers to indicate when key events occurred while the logger was sampling, for example when the logger was placed in a controlled environment, or to indicate when some unexpected event was observed that you suspect might be influencing the temperature.
