Setting Operand Parameters
The parameters that you need to enter depend on whether the function is followed by “( , )” or “( )”.
• Setting Parameters for Functions Followed by “( , )”
Specify the element to the left of the comma, and specify the harmonic order to the right of the comma. For
example: (E1,OR2).
• Symbols used to represent elements
E1 to E6:
Elements 1 to 6
E7 to E9: Wiring units ΣA to ΣC
• Symbols that indicate the harmonic order (Order)
*
ORT: Total value
OR0: dc
OR1: Fundamental wave
OR2 to OR500: Harmonic orders 2 to 500
* On models with the harmonic measurement option or the simultaneous dual harmonic measurement
option.
• Setting Parameters for Functions Followed by “( )”
Specify the element.
You do not need to specify a harmonic order. For example: (E1).
For information about the parameters that you can use with each operand, see appendix 6 in the getting started
guide, IM WT1801-03EN.
