Selecting Auto or Manual OTDR Mode - DTX Compact OTDR Module

Typically, you should use Auto OTDR mode when certifying cabling with the OTDR.

  • From the HOME screen, press F3 Change Test; then select Auto or Manual.
    • In Auto OTDR mode, the tester automatically selects certain settings based on the length and overall loss of the cabling. This mode is the easiest to use, provides the most comprehensive view of the events on the cabling, and is the best choice for most applications.
    • Manual OTDR mode lets you select the settings to optimize the OTDR for displaying specific events.
