Trigger
Trigger source set up:

Events – triggered by voltage event (see 3.23.2);

Alarms – triggered by alarm activation (see 3.23.3);

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). Interval between two-time triggered
waveforms in Interval trigger type
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.
Store mode
Store mode setup:

Single – waveform recording ends after first trigger;

Continuous (Max. 1500 record)– consecutive waveform
recording until user stops the measurement or instrument
runs out of storage memory. Every consecutive waveform
recording will be treated as a separate record. By default, 200
