Trigger
Trigger source set up:
Events – triggered by voltage event (see 3.21.2);
Alarms – triggered by alarm activation (see 3.21.3);
Events & Alarms – triggered by alarm or event;
Level U – triggered by voltage level;
Level I – triggered by current level (inrush).
Interval – periodical trigger for given time period (each 10
minutes for example).
Level*
Voltage or current level in % of nominal voltage or current and in (V
or A), which will trigger recording
Slope*
Rise – triggering will occur only if voltage or current rise
above given level
Fall - triggering will occur only if voltage or current fall below
given level
Any – triggering will occur if voltage or current rise above or
fall below given level
Duration
Record length.
Pretrigger
Recorded interval before triggering occurs.
Interval
Interval between two time triggered waveforms in Interval trigger
type
Store mode
