Basic Operation
⚫
Cyclic Display
In cyclic display, display and phases automatically change at every 5 seconds.
When
is pressed for about 2 seconds, the cyclic display appears.
When
is pressed for about 2 seconds, the cyclic phase appears.
By pressing any other buttons except , cyclic display mode ends.
⚫
Harmonics display
Harmonic RMS value and distortion ratio can be displayed.
It is necessary to set the harmonics display settings before displaying.(Refer to page 22)
