Using TEDS Server
Note that TEDS Server can only be used with Dragonflies that have TEDS compatible signal conditioning. Also, there must be an application running called "TEDS Server." Lastly, there may be slight differences in necessary set up steps seen in the video depending on the version of software used. However, TEDS is used in the same way for all software versions.
Go to the "Channel Config" page and setup a configuration. Make sure to go to the signal conditioning page and adjust settings as necessary.

Next click on the tab with the type of calibratibon used (SPL, mV/EU, etc). Click on the button in the lower right corner labeled "TEDS." 
On the pop up window click "Refresh TEDS."

Double clicking on a URN will give you detailed information about the device.
You can apply the calibration values to a channel directly from this window if you would like by selecting the channel and then clicking "Apply to Channel."
From the Node URN's page you may also select "Auto Setup Channels" to automatically apply the TEDS values found.
