The reference signal can also be used for further processing with I/Os, like e.g. subtracting the current signal from a reference from a previous measurement of the same signal, to see the changes in the signal.
Properties and actions
To control the behavior of the Reference I/O, several properties and actions are available. These can be accessed through a popup menu which is shown when the I/O is right clicked in the Object Tree. The properties can also be accessed through its settings window which is shown when the I/O is double clicked in the Object Tree. To open the Object tree, click the Show object tree button.
By default, the settings window only shows the most used settings. When Advanced is ticked, the extended window with all settings is shown. See also the program settings.
The Copy action can be used to copy new data from the life signal into the reference, renewing the Reference data.
