This document is the operation manual for Optical Wavelength Laboratories optical power meters FO-4B and FO-4V. The optical power meter features high accuracy, high resolution, and microprocessor control, and can perform measurements such as optical power and attenuation as well as fiber optic link certification. It is suitable for various fiber optic testing environments and comes with a durable housing and convenient battery replacement feature.
This manual introduces the FO-4 series optical power meters, describing safety precautions, product identification, and basic features. It explains how to safely handle the high‑power laser source, keep connectors clean, and avoid eye injury.
The guide covers operation procedures such as active equipment power testing, fiber continuity checks, attenuation measurement, and length testing using the built‑in loop‑back method. It also details data management, USB download, and report printing functions. This manual is written in Chinese.
