The RMS I/O returns one value, which is the mean value of the RMS values of the individual periods in the input signal.
A typical application of the RMS I/O is logging RMS values to monitor e.g. mains voltage.
To control the behavior of the RMS I/O, several properties 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.
