Data logs

When you need details about circuit measurements and details, the Area Details diagram provides links to the historical data log and the event log. These logs provide measurement data for the 5-minute polling interval of the LIM-IG6. You can filter the data in the logs by date range.

When using the event log, you can also generate a graph that shows THC measurements plotted across time. If any THC measurement exceeds the hazard threshold, the graph includes a callout at the specific event point.

Historical data log and graph

The following figure shows the historical log table.

The buttons located at the top of the table are:

• Device Diagram – Click this to return to the diagram.
• Change Date Range – Click this to view data for different dates. See "Select Date Range" below for more information.
• Show Graph – Select one or more column headers in the table and click this to see a graph of the data. The graph shows the data at 5-minute intervals. For example, you can check the Total Hazard Current option in the table and see the values. Click a point on the data line to see details for that value, as shown next.
