Changing a Measurement Function
• The types of measurement functions that can be selected are the functions described
in “Types of Measurement Functions Used in Normal Measurement” and “Measurement
Functions Used in Harmonic Measurement (Optional)” in section 2.2, in “User-Defined
Functions” in section 2.5, in “Integration Functions” in section 2.6, and in “Delta
Computation (Optional)” in section 5.17.
•
You can also choose not to display a measurement function (None).
• The numbers (1, 2, 3, and 4) that are attached to delta computation measurement
function symbols are a part of the symbols and have no relation to the element
numbers.
•
The numbers attached to user-defined functions F1 to F8 are a part of the
measurement function symbols and are not related to the element numbers.
Changing the Element or Wiring Unit
• You can select the element/wiring unit from the choices below. The selectable items
vary depending on the number of elements installed in the WT500.
Element1, Element2, Element3, and
Σ
•
If there are no elements that are assigned to the selected wiring unit, because there is
no numeric data,
Σ
measurement functions will display “-------” (no data).
