  • a measurement unit to measure a first time period taken until a reflection signal is received after a first signal is output to the test apparatus;

    a memory including a first unit and a second unit, the first unit being capable of storing CAD data of the test apparatus, the second unit being capable of storing model data indicating a relation between the first time period and a conduction distance of the first signal;

    a controller configured to calculate a test, object selected in the test, apparatus based on the CAD data, calculate the conduction distance based on the first time period, and specify a position of a fault, the position being separated by the conduction distance from the measurement unit; and

    a display configured to display the CAD data and the position of the fault in the CAD data.
