• You can also select not to display the measurement functions (None).
• The number (1, 2, 3, and 4) that is attached to the measurement function symbol of
the delta computation has no relation to the element number.
• The number attached to the user-defined function F1 to F20 is a portion of the
measurement function symbol. It is not related to the element number.
• Changing the Element/Wiring Unit
• You can select the element/wiring unit from the choices below. The selectable
items vary depending on the installed elements.
Element1, Element2, Element3, Element4,
Σ
A, and
Σ
B
• If there are no elements that are assigned to the selected wiring unit, there is no
numeric data. Thus, [-------] (no data) is displayed in this case. For example, if
elements are assigned to
Σ
A and no elements are assigned to
Σ
B, then the
measurement function for
Σ
B shows [-------] (no data).

Note
•
For the meanings of the measurement function symbols that are displayed, see section 2.2,
“Measurement Functions and Measurement Periods,” 2.5, “Computation,” 2.6, “Integration,”
appendix 1, “Symbols and Determination of Measurement Functions,” and chapter 6, “Delta
Computation” in the
Expansion Function User’s Manual IM760301-51E
.
•
For the procedure of changing the displayed items of the measurement functions of harmonic
measurement, see chapter 7 in the
Expansion Function User’s Manual IM760301-51E
.
•
For details on the wiring units expressed as
Σ
A and
Σ
B, see section 4.1, “Selecting the Wiring
System.”
•
If you supply current exceeding approximately 2.8 Arms to the 2-A input element, the
protection circuit activates. The measured value may become 0 A, but the input peak over-
range indicator at the top section of the screen illuminates in red.
