Lightweight power meter series product mainly used for tracking measurement of optical signal capacity and closed-open testing through optical fiber path. It uses a single chip microprocessor to perform control and has complete functionality. It has been widely used in the construction and maintenance of optical cables, fiber optic communication, optical cable detection, CAT light fields, etc. The design of the machine body models conforms to the technical requirements of the human body, and it uses advanced cold casting technology, it is beautiful and practical. The power meter uses a built-in detector and laser, which protects it very well. The lightweight power meter has a delicate appearance, automatic shutdown, three types of backlight mode, wavelength memory function, optical fiber work recognition, manual calibration, and wide test range. Features: Accurately test whether a single network cable transmits signals normally. Add flashlight lighting function to LED for easy line inspection in dark environments. Add wavelength memory function to remember the set test wavelength before shutdown after shutdown. An encapsulated housing protection can reduce the damage to the machine caused by accidental drops to a certain extent. Press LIGHT in different environments to turn the backlight on or off at will. You can perform automatic adjustment test reference according to actual test requirements.
