Measuring Power or Loss (FPM-600 and FOT-600)

Power Meter/Light Source/Optical Loss Test Set 25

Referencing Your Power Meter to a Source

To reference the power meter to a source manually:

1. Using the proper adapter, connect a light source (such as FLS-600 or

FOT-600) to the detector port of your power meter.

2. Activate the source at the desired wavelength.

3. Match the source and power meter

wavelengths:

 If the source emits an auto-wavelength

signal or is in auto-switching mode (see

Automatically Detecting Wavelength on

page 29 and Using Auto-Switching Mode

on page 35), the power meter automatically matches the source

wavelength.

 Press to switch between pre-selected wavelengths (see

Defining a List of Favorite Wavelengths on page 22).

4. Hold down for a few seconds. The

power meter stores the currently detected

power as the new reference power.

Reference power is displayed in the top

right corner (in dBm) and current loss

reading is automatically switched to dB.
