Page 16: Set Wavelength
Chapter 7 Fault Locator Operation 7.0 Fault Locator The Fault Locator is a simple autotest feature which displays the test results in event table with the schematic view. The fault locator will take a scan of the fiber in auto test mode. The user sets the wavelength to be tested and the OTDR will set the pulse width and range to best suite the fiber under test at the selected wavelength. The average time will be set to 15 seconds. 7.1 Fault Locator Operation To enter the Fault Locator mode, touch the FAULT icon on the home screen. - Page 17 Chapter 7 Fault Locate Operation 7.1 Fault Locator Operation Continued When a scan it taken with the Fault Locate, the trace information is temporarily stored in the OTDR. If the full trace needs to be viewed, double touch in the event table area or press the Menu button to return to the home screen.

Chapter 8 OTDR Operation Note When setting the range and pulse width, it is necessary to keep in mind that it may not be beneficial to use certain pulse widths with some ranges. For this reason not all pulse widths are available for use with all rangers. -
Page 28: Construction Mode
Chapter 8 OTDR Operation Construction Mode Construction Mode is useful when a large number of fibers need to be tested with the same settings at multiple wavelengths. This mode tests a fiber at two wavelengths, saves the traces and displays them in dual trace mode. Create or Open a Project Press the menu button, use the right or left buttons to highlight the Project Management folder icon and press select. Use the up and down buttons to highlight the desire project and press Select, or create a new project once you have established all the desired parameters for testing. - Page 29 Chapter 8 OTDR Operation Set the Wavelengths On the main trace screen in the OTDR tab the wavelength settings are accessible.
