The presented list of display functions are based on the current selection of measurement functions.
Only the available time constants for the selected function are displayed.
The function list offered depends of the functions measured and the type of graph you are configuring.
If you are missing some functions here (e.g. a network or time weighting), please enter the SETUP Measurement menu system and see if
the parameter is turned on and that the desired function is activated.
If you change ome settings in the measurment setup, it might end in display functions not measured.
