Figure 75: Configuring measurement items
• Apply custom scaling, if needed.
1. In the scaling box, define the correct value which is a coefficient applied to
the measurement value. The supported scaling is linear: new_value =
read_measurement_value × scaling_property + offset_property.
2. In the offset box, define the offset value.
3. In the unit box, define the unit (string).
4. Adjust the other limit properties to better fit the scaled measurement value.
• In the order box, define custom order for the measurements, if needed.
The smaller the order property, the higher the measurement's position in the
measurement list.
By default, all measurement list items are arranged in alphabetical order.
Modifying the order property overrides the default behavior.

Phasors page

By default, the Phasors page template available in Page Organizer contains an empty
Custom signal group. Measurements can be added to the Custom signal group or new
signal groups can be added and removed by opening the Phasors page in Page Editor.
Opening Signal Grouping Editor
1. In Page Editor, open the Phasors page.
2.
Click in the lower-right corner of the Phasors page.
