2. Varnostne informacije

• Preberite priročnik: Before operating the device, thoroughly read and understand this user manual.
• Varnost baterije: Use only specified 1.5V batteries (3x AAA). Do not mix old and new batteries or different types of batteries. Remove batteries if the device will not be used for an extended period.
• Laserska varnost: The optical light source emits laser radiation. NE look directly into the optical output port or into a fiber connected to the light source. Direct exposure to laser light can cause severe eye damage.
• Okoljski pogoji: Operate the device within the specified operating temperature range (-10°C to +60°C). Avoid exposure to extreme temperatures, humidity, or dust.
• Čiščenje: Keep optical connectors clean. Use only approved cleaning methods and materials to avoid damaging the fiber end-faces.
• Vzdrževanje: Ne poskušajte odpirati ali popravljati naprave. Vsa servisna dela prepustite usposobljenemu osebju.

5. Nastavitev

5.1 Namestitev baterije

1. Poiščite pokrov predalčka za baterije na zadnji strani naprave.
2. Potisnite ali odpnite pokrov, da ga odprete.
3. Vstavite tri (3) 1.5 V baterije AAA in pri tem pazite na pravilno polarnost (+/-), kot je označeno v notranjosti predala.
4. Varno namestite pokrov prostora za baterije.

5.2 Začetni vklop

Pritisnite in držite Moč button to turn on the device. The LCD display will illuminate, showing the current mode and settings.

6. Navodila za uporabo

6.1 Optical Power Meter Mode

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

1. Povežite se z optičnimi vlakni: Connect the optical fiber to be tested to the Power Meter input port. Ensure the connector is clean.
2. Izberite valovno dolžino: Pritisnite λ button to cycle through the available calibrated wavelengths: 850nm, 1300nm, 1310nm, 1490nm, 1550nm, 1625nm. Select the wavelength matching your light source.
3. View Merjenje: The display will show the optical power in dBm.
4. Change Unit: Pritisnite dBm/W button to switch between dBm and W (Watts) units.
5. 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.
6. 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.

1. Povežite se z optičnimi vlakni: Connect the optical fiber to be tested to the Light Source output port. Ensure the connector is clean.
2. Izberite valovno dolžino: Pritisnite λ button to cycle through the available wavelengths: 1310nm and 1550nm. Select the desired wavelength.
3. Select Modulation Frequency: Pritisnite Hz button to cycle through modulation frequencies: 270Hz, 1KHz, 2KHz, or continuous wave (CW).
4. Izhodni signal: The device will emit a stable optical signal at the selected wavelength and modulation.

6.3 Funkcija samodejnega izklopa

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 Moč gumb, da ga znova vklopite.

7. Vzdrževanje

• Čiščenje optičnih konektorjev: 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.
• Zamenjava baterije: When the battery indicator on the display shows low power, replace all three 1.5V AAA batteries promptly.
• Shranjevanje: 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.
• Zunanje čiščenje: Zunanjost naprave očistite z mehko, damp krpo. Ne uporabljajte abrazivnih čistil ali topil.

8. Odpravljanje težav

• Naprava se ne vklopi:
  • Preverite, ali so baterije pravilno vstavljene s pravilno polarnostjo.
  • Zamenjajte s svežimi baterijami.
• 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.
• No light output from light source:
  • Ensure the device is powered on and in light source mode.
  • Preverite nivo baterije.
  • Verify the fiber is properly connected to the output port.
• Auto-off activates too quickly:
  • The auto-off is fixed at 15 minutes of inactivity. This is normal operation.
