5. Enstalasyon
5.1 Enstalasyon batri
- Jwenn kouvèti konpatiman batri a sou dèyè aparèy la.
- Glise oswa deklipe kouvèti a pou louvri li.
- Insert three (3) 1.5V AAA batteries, ensuring correct polarity (+/-) as indicated inside the compartment.
- Ranplase kouvèti lòj batri a byen.
5.2 Premye pouvwa sou
Peze epi kenbe la Pouvwa button to turn on the device. The LCD display will illuminate, showing the current mode and settings.
6. Operasyon Enstriksyon
6.1 Optical Power Meter Mode
This mode measures the absolute optical power or relative loss in optical fiber networks.
- Connect Fiber: Connect the optical fiber to be tested to the Power Meter input port. Ensure the connector is clean.
- Chwazi longèdonn: Peze a λ button to cycle through the available calibrated wavelengths: 850nm, 1300nm, 1310nm, 1490nm, 1550nm, 1625nm. Select the wavelength matching your light source.
- View Mezi: The display will show the optical power in dBm.
- Change Unit: Peze a dBm/W button to switch between dBm and W (Watts) units.
- Set Reference (REF): For relative measurements (loss), connect a known good fiber to a stable light source and the power meter. Press the REF button to set the current power reading as the reference (0dB). Subsequent measurements will show the loss relative to this reference.
- Frequency Identification: The power meter can identify modulation frequencies from 10Hz to 60KHz. If the incoming signal is modulated, the frequency will be displayed.
6.2 Optical Light Source Mode
This mode provides a stable optical signal for testing fiber optic cables.
- Connect Fiber: Connect the optical fiber to be tested to the Light Source output port. Ensure the connector is clean.
- Chwazi longèdonn: Peze a λ button to cycle through the available wavelengths: 1310nm and 1550nm. Select the desired wavelength.
- Select Modulation Frequency: Peze a Hz button to cycle through modulation frequencies: 270Hz, 1KHz, 2KHz, or continuous wave (CW).
- Siyal Sòti: The device will emit a stable optical signal at the selected wavelength and modulation.
6.3 Fonksyon Auto-Off
The device features an auto-off function to conserve battery life. If no operation is performed for approximately 15 minutes, the device will automatically power off. Press the Pouvwa bouton pou vire l tounen sou.
7. Antretyen
- Cleaning Optical Connectors: Always ensure optical connectors are clean before use. Use lint-free wipes and appropriate optical cleaning solutions. Dirty connectors can lead to inaccurate measurements and damage to the device or fiber.
- Ranplasman batri: When the battery indicator on the display shows low power, replace all three 1.5V AAA batteries promptly.
- Depo: When not in use, store the device in a dry, cool place, away from direct sunlight and extreme temperatures. Always replace the protective caps on the optical ports to prevent dust and damage.

NAN. Depanaj
- Aparèy la pa limen:
- Tcheke si pil yo byen enstale ak polarite ki kòrèk la.
- Ranplase ak pil fre.
- Inaccurate power meter readings:
- Ensure optical connectors are clean.
- Verify the selected wavelength on the power meter matches the light source wavelength.
- Check if the fiber under test is properly connected and not damaged.
