History
Contains a list of all events and transients recorded by the same device (History of Device). You use History to open a CBEMA chart for the corresponding device.
CBEMA Chart
By activating the checkbox, you open a CBEMA chart for the voltage events of the selected device. You use the input field to adjust the nominal voltage that serves as the reference point for the chart.
History of Device
If filters are active, they are listed in the header of the History of Device and can be removed here or temporarily deactivated by clicking on them.
By clicking on an element from the list, it is selected and displayed in the header (Fig.1 1) and in the measure value or CBEMA chart.
Three-phase event
Some measurement devices also record three-phase events in addition to the single-phase events. If an event occurs in all three phases, these three events are combined into a three-phase event.
- Three-phase events can be identified by the red border around the event icon.
- Three-phase events are not included in the CBEMA chart.
