Live Readouts

Each sensor has an associated column where that sensor's data is displayed.  Live readouts are values that are taken approximately 5 times a second (if you are collecting at a slower rate, the live readouts will be updated at the same frequency as the collection) and displayed with each sensor's column name in the second row of the toolbar next to the icon for the interface that the sensor is attached to.



Live readouts for calculated columns that are based on sensor columns are also displayed here.  You can turn live readouts on or off for any sensor column or calculated column that depends on a sensor column via a checkbox in the column options dialog.

The motion detector makes a distracting noise when taking its reading, so by default its sensor column (Position) and calculated columns (Velocity, Acceleration) have live readouts turned off.

Sensors will only report their state at the instant the live readout is taken.  Intermediate values will not be displayed.

Calculated columns that depend on more than one point for their display (e.g. Velocity) will not report live readouts since a live readout is by definition a single value.  However, while you are doing a data collection the live readout display will show the most recently collected point, and thus this type calculated column will show a value.

You can turn live readouts on or off from the Experiment menu.

While live readouts are on, the application automatically polls each device to see if sensors have been added or removed.  When it detects that a sensor has been removed, the application will delete the associated sensor column unless that column has data in it.  When the application detects that a sensor has been added, it will add the appropriate sensor column.  If you do not like this sensor polling, you can prevent it by turning live readouts off.
