press Enter.

2. Display the Acquisition pane (F1/F2 key).

3. Use the up/down arrows to select the

wavelength box, and then press Enter to

open it.

4. Select the wavelength for which you want to modify parameters. Press

Enter to confirm your choice.

5. Use the arrows to select any of the settings, and then press Enter to

display the on-screen keyboard (for details about using keyboards, see

Using Menus and Keypad on page 13).

6. Enter the new value and press OK (F1/F2 key).

IMPORTANT

Do not change the default backscatter parameter unless you have

values provided by the fiber manufacturer. If you set this parameter

incorrectly, your reflectance measurements will be inaccurate.
