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 50Hz, up to 50 orders can be displayed;
• When the fundamental frequency is 400Hz, 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 Ch. 15 for more details on upper limits of analysis orders.
