6. මෙහෙයුම් උපදෙස්

6.1 Optical Power Meter Mode

This mode measures the absolute optical power or relative loss in optical fiber networks.

1. Connect Fiber: Connect the optical fiber to be tested to the Power Meter input port. Ensure the connector is clean.
2. තරංග ආයාමය තෝරන්න: ඔබන්න λ button to cycle through the available calibrated wavelengths: 850nm, 1300nm, 1310nm, 1490nm, 1550nm, 1625nm. Select the wavelength matching your light source.
3. View මිනුම්: The display will show the optical power in dBm.
4. Change Unit: ඔබන්න dBm/W button to switch between dBm and W (Watts) units.
