Application work area
UM1719
The application work area is divided into several sections logically grouping the relevant
information of the device.
In this way, the status of the device and the data of registers are always available to the user
at a single glance.

3.1
Device selection
On the top left of the work area, a group-box is available to select the device. The
application work area changes according to the selected device’s features.
3.2
Calculated values
On the topmost section of the work area, all data are available, such as:
1. Energy and power values
2. RMS and instantaneous (wide-band and fundamental) values of voltage and current
3. Line voltage frequency
4. Information about sag and swell events
Status and event bit check boxes are close to the information they refer to; event bits are
read only, because they are updated by the device DSP, while status bits are enabled since
they are set by the DSP but they must be cleared by the user. He can clear status bits either
unchecking the single check box and then pressing the "Write" button (the configuration and
