5. Rêwerzên Sazkirinê
5.1. Sazkirina Pîl
- Locate the battery compartment on the back of the KPV-53 device.
- Berga beşa pîlê vekin.
- Insert three (3) AAA 1.5V alkaline batteries, ensuring correct polarity.
- Qapaxa beşa pîlê bi ewlehî bigire.
5.2. Connecting Fiber Optic Cables
The KPV-53 features a 2.5mm universal interface for the Optical Power Meter and a dedicated port for the Visual Fault Locator. Ensure to use the correct adapter for your fiber type.
- Remove the dust cap from the desired port (OPM or VFL).
- Clean the fiber optic connector end-face thoroughly using appropriate fiber cleaning tools.
- Insert the cleaned fiber optic connector into the device port. For OPM, the standard connector is SC UPC, but adapters for FC, ST, and LC are available (optional).
- Têkiliyek ewle ewle bikin.
