Disturb rec
The disturbance recorder works with 32 samples per cycle. The disturbance recorder can be started by one of
eight start events (selection from the »assignment list«/OR-Logic). The disturbance record contains the
measuring values inclusively pre-trigger-time. By means of Smart View/Datavisualizer (option) the oscillographic
curves of the analogue (current, voltage) and digital channels/traces can be shown and evaluated in a graphical
form. The disturbance recorder has a storage capacity of 120s. The disturbance recorder is able to record up to
10 s (adjustable) per record. The amount of records depends on the file size of each record.
The disturbance recorder can be parametrized in the menu »Device Parameter/Recorder/Disturb rec« .
Determine the max. recording time to register a disturbance event. The max. total length of a recording is 10s
(inclusive pre-trigger and post-trigger time).
To trigger the disturbance recorder, up to 8 signals can be selected from the »assignment list«. The trigger
events are OR-linked. If a disturbance record is written, a new disturbance record cannot be triggered until all
trigger signals, which have triggered the previous disturbance record, are gone. Recording is only done for the
time the assigned event exists (event controlled), plus the time for the pre- and post-trigger, but not longer than
10s. The time for forward run and tracking of the disturbance recorder is shown in percent of the total recording
length.
The post-trigger time will be up to "Post-trigger time" depending on the
duration of the trigger signal. The post-trigger will be the remaining time of the
"Max file size" but at maximum "Post-trigger time"
