Measuring Power or Loss

Multifunction Loss Tester 37

Measuring Power or Loss

6. Using bulkhead adapters or the system patch panels, connect a fiber

under test to reference patchcords attached to the light source and

power meter.

7. Activate the source at the desired wavelength.

8. 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.

If the unit detects a modulated signal, it beeps and the signal frequency

is indicated in the status bar, next to a yellow LED: 2k indicates a 2-kHz

signal, 1k a 1-kHz signal, and 270 a 270-Hz signal.

9. Press W/dBm/dB (F1/F2 key) to select the desired power (W or dBm)

or loss (dB) unit.
