Operation Modes � Auto mode – For quick and easy-to-use measurement – Most settings will be automatically selected by software. User only needs to set wavelength, measurement unit, IOR. – Provide both OTDR trace and Event table � Advanced (Manual) mode – Allow a user to set pulse width, averaging, distance range – Provide OTDR trace only 8 ELEXO - Téléphone : 01 41 22 10 00 - Fax : 01 41 22 10 01 - info@elexo.fr
