Waveform Recorder
Waveform rec
The waveform recorder works with 32 samples per cycle. It can be started by one of eight start events (selection from
the »Assignment list«/OR-Logic).
The waveform record contains the measuring values including the pre-trigger time. By means of PowerPort-E/Quality
Manager (option), the oscillographic curves of the analog (current, voltage) and digital channels/traces can be shown
and evaluated in a graphical form.
The waveform recorder has a storage capacity of 120 s (duration). The amount of records depends on the file size of
each record.
The waveform recorder can be configured in the
»Device Parameter/Recorder/Waveform rec«
menu.
Determine the maximum recording time to register a waveform event. The maximum total length of a recording is 10 s
(including pre-trigger and post-trigger time).
To trigger the waveform recorder, up to eight signals can be selected from the »Assignment list«. The trigger events
are OR-linked. If a waveform record is written, a new waveform record cannot be triggered until all trigger signals,
which have triggered the previous waveform 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 10 s. The time for the pre- and post-trigger is to be entered as percent of the maximum file
size.
The post-trigger time will be up to the "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, the "Post-trigger time".
Example
The waveform recorder is started by the general activation facility. After the fault has been cleared (plus follow-up
time), the recording process is stopped (but after 10 s at the latest).
The parameter
»Auto Delete«
defines how the device will react if a location to which to save the waveform record is not
available. In case
»Auto Delete«
is
»Active«
, the first recorded waveform will be overwritten according to the FIFO
principle. If the parameter is set to
»Inactive«
, recording of the waveform events will be stopped until the storage
location is manually released.
