Page 20: Length And Reflections
MI 2014 Cable Scanner Section III Cable Scanner operation 12. Length and reflections This function enables accurate cable length and quality measurements. Up to 3 largest reflections caused by cable damages, impedance mismatches or other reasons are also detected. There are many applications where the Length & Reflection test can be used... - Page 21 MI 2014 Cable Scanner Section III Cable Scanner operation Principle of Cable Scanner Length&Reflections operation To encounter the attenuation effect the reflections amplitudes are compared to the normal attenuation line. This means that a reflection with smaller amplitude at higher distance can be treated as higher then a reflection with higher amplitude at the begin of the measuring range.

Page 24: Cable Length Calibrations
MI 2014 Cable Scanner Section III Cable Scanner operation 12.1 Cable Length Calibrations The accuracy of the length measurement is calculated from the time it takes the pulse to travel along the cable and reflect back to the instrument. For this reason the cable NVP (nominal velocity of pulse propagation) must be known. - Page 25 MI 2014 Cable Scanner Section III Cable Scanner operation 1.Select Length&Reflections with rotary switch and press afterwards. The 'Length Calibration' screen is displayed. NVP calibration display 2.Connect the cable of known length to the instrument and set the length with keys.
