This area of the system allows you to inspect triggered captures retrieved from data loggers. A primary use of this is for analysing current from points/switch motor drives.
To view the list of configured captures for a site, start typing the name of the site in the box containing Type Site Name...
The capture listing will contain the captures as configured in the logger's channel mapping. One capture represents one monitored channel, usually monitoring a single end of a set of points.
To view the list of traces (captured events) for a given capture (channel), click on the name of the capture you want to view. This will load all the events that have occurred on this capture channel;
|Date/Time||The date/time the event started|
|Dir||The direction indicator sent by the logger (e.g. N -> R for normal to reverse)|
|Len (sec)||The length of the capture (in seconds)|
The trace listing can be filtered by Direction or Tag.
You can view the traces for a particular day by selecting a date in the Traces listing header.
You can view a trace by clicking thebutton in the Actions column of the trace listing, or by double-clicking on the table row. By default this will add the trace to the current graph (overlaid with any existing traces).
The trace viewer contains a listing of all the selected traces;
|Colour||Colour of the trace on the graph|
|Channel||Capture channel the trace belongs to|
|Date/Time||Date/time the event started|
|Dir||Direction indicator sent by the logger (e.g. N -> R for normal to reverse)|
|Average||Average value of the trace|
|Total||Total area under the curve for the trace|
|Length||Length of the capture (in seconds)|
|Start Trigger||Time the start trigger was fired (if available)|
|End Trigger||Time the end trigger was fired (if available)|
You can perform global actions to the current trace graph using the Actions menu on the top right;
|Export as||Export the current graph as an image|
|Apply area fill||Colour fill the area under the curve|
|Apply line smoothing||Apply line smoothing to the graph series|
|Sync all to end/start||Synchronise the selected traces to the end/start|
|Clear all traces||Remove all the current traces from the graph (reset)|
