Values
You can customize the values associated with the Range dial. Once the
customization is complete, you are ready to set the distance range value
for your test. For more information, see Setting Distance Range, Pulse
Width, and Acquisition Time on page 60.
Note: The value found by an auto acquisition cannot be modified.
To customize the distance range values:
1. From the main window, select the OTDR tab then tap the
button.
2. Under Custom Parameters, if your OTDR supports singlemode or
multimode, specify the desired fiber type.
Note: The fiber type list is not displayed if the module has only one fiber type.
