Abstract
A data storage section stores a plurality of characteristic data obtained by measuring one optical fiber a plurality of number of times at time intervals or a plurality of characteristic data obtained by measuring a plurality of optical fibers. The output unit displays the waveforms of the plurality of characteristic data. A waveform display control section causes the output unit to display the waveforms of the plurality of characteristic data on the orthogonal coordinate plane defined by a distance axis and a characteristic value axis. A reference point designating section designates an arbitrary reference point within the orthogonal coordinate plane. A calculating section calculates the difference between the characteristic value axis coordinate value of the reference point designated by the reference point designating section and the characteristic value axis coordinate value of each of the characteristic data at a distance axis coordinate value nearly equal to the distance axis coordinate value of the reference point. An offset section offsets the characteristic data in the characteristic value axis direction.
