It features superb measurement confidence, ease of use and reduced cost of ownership, and is for use by installers, technicians and engineers. Superior measurement confidence is achieved with a unique Total Uncertainty specification over the full temperature , measurement and connector range, and a NATA traceable calibration certificate. The display hold and back light facilities help acquire readings, and the flexible memory helps record your results Autotest mode enables automatic l (wavelength) detection and attenuation measurement (in combination with an Autotest source). A single or dual l source and meter in Autotest mode automatically measure single or dual l attenuation in one direction. High operational reliability & availability is achieved with 250 hour battery life, 3 year recommended re-calibration cycle, negligible warm up and no range-changing delays. Dark current offset is not required. An external power input is also provided. The combination of features enables reduced equipment inventory, simpler training, shorter procedures, lower skill levels and direct labour savings in many situations, combining to give lower cost of ownership. The innovative optical connector port provides drop protection during use, and is dust protected by a snap on cover. The interchangeable optical connector system is very versatile, and easily disassembled for cleaning. ...
