TIP
The Instant Setting screen page 2/2 of Harmonics Measure mode partially shares the same setup data
items with the System Setting screen page 1/2. Consequently, you can change these setup data items
of the System Setting screen by pressing the key in Harmonics Measure mode, rather than by
calling the TOP MENU screen and then the System Setting screen.
