5KM Visual Fault Locator Optical Power Meter Handheld VFL Fiber Optic Cable Tester ‑70‑6dbm

Feature: 1. 2 Backlight Modes: Default smart mode after startup, the backlight will be automatically turned off without operation for 3 minutes. In the off mode, press the LED key to switch to smart mode. 2. Wavelength Memory: The wavelength testing range of this optical power meter is 800‑1700nm, with an added wavelength memory function to remember the test wavelength set before shutting down. 3. Frequency Identification: Can accurately identify the transmission frequency of optical fiber, used to determine the lighting mode and whether it is continuous or intermittent during engineering construction. 4. Other Functions: Supports FC, SC, ST common fiber interfaces, detachable metal pen tip for easy replacement of ceramic core, and automatically shuts down after 10 minutes of no operation. 5. Units Switching: Press the UNIT key to select dBm, dB, and uW units in turn, and the test data will be displayed in the corresponding results, which is convenient and practical.
