 Optimized for power measurements on fiber optic systems based on single-mode, multimode, plastic or large core glass optical fibers and using near-infrared or visible light sources. Operation is simple and user friendly, with three buttons to control all essential functions. It is rugged and splashproof, with a rubber boot to protect against dropping and crushing. Its multi-wavelength reference stores and recalls reference power levels for faster, more efficient measurement. It has 635nm, 780nm and 850nm calibration wavelengths, and a +3dBm to -60dBm measurement range with an 0.01dB measurement resolution and a 3 x 3.5mm Silicone detector. Relative logarithmic dB and absolute logarithmic dBm units. User select shut-off. Powered by two AA batteries for over 100 hours, or an AC power converter/adapter for prolonged benchtop use. 60553 557B
