Functions with parentheses will produce different values depending on which of the following is contained in their
parentheses.
• Total: Total value (The total value of all harmonic components from the minimum order to N.* For information
about how the value is determined, see appendix 12 in the Getting Started Guide, IM WT5000-03EN.)
• 0(DC): DC value
• 1: Fundamental harmonic value
• k: The value of any order from 2 to N.*
* N is the maximum measurable order. he maximum measurable harmonic order is the smallest of the three
orders listed below.
• The specified maximum measurable harmonic order
• The value determined automatically according to the PLL source frequency (see section 6.7 in the Getting
Started Guide, IM WT5000-03EN)
• When the data update interval is 50 ms or Auto, the maximum measurable harmonic order is 100.
