Capturing Data & Troubleshooting
Occasionally, you may need to troubleshoot a difficult equipment problem. You can use the Tracer
TU Data Logging Utility to view data at your desired sampling rate with no memory limitations
besides your laptop hard drive or USB jump drive.
To capture data in a live session log
1. If you are already in Tracer TU service tool and connected to a controller, but you have not yet
configured a session log, click the Data Log tab on the right side of the Tracer TU service tool
window. The View Graphs and Session Log tabs appear across the top of the viewing area.
2. Click the Session Log tab.
3. Set the time interval between samples on the Sampling Rate spin box. This setting specifies
how often Tracer TU captures a snapshot of the selected data points. (For example, a data
capture could occur every five seconds, 15 minutes, or once every hour.)
4. Select the Automatically Name Session Log check box to use a system-generated location and
file name or click the Browse button to specify an alternate path and filename.
5. Select a major category from the Categories drop-down list if you want to log only a subset of
the available data points.
6. Select individual data points or groups of data points for logging by using the arrow controls.
For Example:
To transfer just a few items from the Available Data box to the Selected Data box, highlight a
data point you want to log, then click the single right arrow key ( > ) to transfer it to the Selected
Data box. Repeat for each data point you want to transfer. (You can also highlight several data
points at once by pressing Ctrl while clicking each item with your mouse.)
