7. Operating Instructions
Fiber Preparation:
- Strip the Fiber: Use the Miller stripper to remove the fiber coating to the required length.
- Clean the Fiber: Use the alcohol bottle and a clean wipe to thoroughly clean the bare fiber.
- Cleave the Fiber: Place the cleaned fiber into the S07 Fiber Cleaver and perform a precise cleave. Ensure the cleaved end is perfectly flat and perpendicular.
Splicing Process:
- Place Fibers: Open the splicer's cover and carefully place the prepared fibers into the V-grooves of the 3-in-1 fiber holder. Ensure the fiber ends are positioned correctly near the electrodes.
- Close Cover: Close the splicer cover. The device will automatically align the fibers.
- Start Splicing: The splicer will initiate the arc discharge and complete the fusion splice. Monitor the process on the LCD display.
- Inspect Splice: After splicing, the device will display the splice loss. Visually inspect the splice for quality.
Heat Shrinking:
- Position Sleeve: Slide a splice protection sleeve over the spliced fiber.
- Place in Oven: Carefully place the fiber with the protection sleeve into the heating oven.
- Start Heating: Close the oven cover. The device will automatically heat the sleeve.
- Cool Down: Once heating is complete, remove the fiber and allow the sleeve to cool and harden.
8. Maintenance
- Clean Electrodes: Regularly clean the electrodes with a cotton swab and alcohol to ensure consistent arc discharge. Replace electrodes when worn.
- Clean V-Grooves and Lenses: Use a soft brush and alcohol to clean the V-grooves and observation lenses to maintain accurate fiber alignment.
- Battery Care: Charge the battery regularly, even when not in use, to prolong its lifespan. Avoid fully discharging the battery.
- Software Updates: Check the manufacturer's website or mobile application for any available software updates to ensure optimal performance and new features.
- Storage: Store the splicer in its protective case in a dry, dust-free environment when not in use.
9. Troubleshooting
If you encounter issues, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| High splice loss | Dirty fiber ends, poor cleave, worn electrodes, dirty V-grooves. | Reclean and recleave fibers. Clean electrodes and V-grooves. Replace electrodes if necessary. |
| Splicer not powering on | Low battery, faulty power adapter, device malfunction. | Charge the battery. Check power adapter connection. Contact support if issue persists. |
| Fiber not aligning | Dirty V-grooves, damaged fiber holders, fiber not placed correctly. | Clean V-grooves. Ensure fibers are seated properly. |
| Heating oven not working | Oven door not closed properly, heating element fault. | Ensure oven door is fully closed. Contact support if issue persists. |
