Explanation
Setting the Order of Harmonics
The maximum order for which analysis results can be displayed varies depending on
the frequency of the fundamental.
Example
• When the fundamental frequency is 50 Hz, up to 50 orders can be displayed;
• When the fundamental frequency is 400 Hz, up to 30 orders can be displayed.
When an order is set exceeding the maximum order, display B will change to the dot
display. Refer to Chapter 16 for more details on upper limits of analysis orders.
