To reference the power meter to a source:

1. Press Menu, then select Power Meter.

2. Check your fibers and clean them properly for optimum performance

(see Cleaning and Connecting Optical Fibers on page 22).

3. Using one of the following methods, connect a light source to the

power meter port of your unit.

 One single reference patchcord

 Two reference patchcords and a bulkhead adapter

4. Activate the source at the desired wavelength.

5. Match the power meter wavelength with the

source wavelength as follows:

 Press Wavelength (F1/F2 key) to switch

between favorite wavelengths of your

power meter (see Defining the List of

Favorite Wavelengths on page 30).

 If the source emits an auto-wavelength signal and auto-detection is

enabled (see Automatically Detecting Wavelength on page 39), the

power meter automatically matches the source wavelength.
