5.1 Displaying Numeric Data and Changing the Displayed Items • Changing the Measurement Function • The types of measurement functions that can be selected are the items that are indicated in “Types of Measurement Functions during Normal Measurement” of section 2.2, “User-Defined Function” and Corrected Power of section 2.5, “Measurement Functions of Integration,” “Motor Evaluation Function (Motor Version)*,” “Delta Computation (Option)*,” and “Harmonic Measurement (Option)*” in section 2.6. * For details, see the Expansion Function User’s Manual IM760301-51E. • 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, ΣA, and ΣB • 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 ΣA and no elements are assigned to ΣB, then the measurement function for ΣB shows [-------] (no data). Change the measurement function of the third item Change the element of the third item • Resetting the Order of Display Items You can reset the displayed order of numeric data to a preset order. For details on the reset items, see appendix 2, “List of Initial Settings and Display Order of Numeric Data.” Note • • • • 5-8 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 ΣA and ΣB, 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 overrange indicator at the top section of the screen illuminates in red. IM 760301-01E
