Ceisiadau
The Alonefire SV57 UV Blacklight is versatile and can be used for various detection and inspection tasks:
- Canfod wrin anifeiliaid anwes: Illuminate dark areas to reveal hidden pet stains on carpets, furniture, or floors.
- Dilysu Arian Cyfred a Dogfennau: Check security features on banknotes, passports, and other official documents that fluoresce under UV light.
- Mineral and Gemstone Inspection: Observe the fluorescence of certain minerals and gemstones for identification or appraisal.
- Archwiliad Ystafell Gwesty: Identify unsanitary spots or hidden stains in hotel rooms.
- Canfod Scorpion: Scorpions are known to fluoresce under UV light, making them easier to spot in dark environments.
- Cat Fungus (Ringworm) Detection: Certain types of fungal infections in cats (like Microsporum canis) may fluoresce under a Wood's lamp (UV light). Consult a veterinarian for diagnosis.
- Anisakis Detection in Fish: While some sources suggest UV light for detecting Anisakis larvae in fish, it is not a definitive method. Always cook fish thoroughly to eliminate parasites.

Black Filter Lens Technology
The SV57 is equipped with a specialized black filter optical lens. This lens is designed to block most visible light, allowing only the pure 365nm UV light to pass through. This results in a clearer and more effective fluorescence, enhancing the visibility of UV-reactive materials.

365nm vs. 395nm UV Light
The 365nm wavelength is considered optimal for many UV detection tasks as it produces a purer UV light with less visible purple glow compared to 395nm UV lights. This allows for clearer observation of fluorescent reactions without interference from the light itself.

Cynnal a chadw
- Glanhau: Sychwch gorff y fflachlamp gyda lliain meddal, damp brethyn. Peidiwch â defnyddio glanhawyr neu doddyddion sgraffiniol.
- Gofal Lens: Gently clean the lens with a lens cleaning cloth to remove dust or smudges.
- Storio: Storiwch y ddyfais mewn lle oer, sych i ffwrdd o olau haul uniongyrchol a thymheredd eithafol.
- Gofal Batri: I gael bywyd batri gorau posibl, gwefrwch y ddyfais yn rheolaidd, hyd yn oed os nad yw'n cael ei defnyddio'n aml. Osgowch ollwng y batri'n llwyr am gyfnodau hir.
Datrys problemau
- Dyfais ddim yn troi ymlaen: Ensure the battery is charged. Connect to a power source and check the charging indicator.
- Allbwn golau UV gwan: The battery might be low. Recharge the device. Ensure the lens is clean and free of obstructions.
- Nid yw codi tâl yn gweithio: Check the USB-C cable for damage. Try a different USB power source. Ensure the cable is fully inserted into both the device and the power source.
- Amlygiad dŵr: The device is IP5 rated for water resistance (splash-proof), but not waterproof for submersion. If it gets wet, dry it thoroughly before use. Do not attempt to charge if wet.
