Abstract:
An electrical wiring system testing apparatus for testing connected states of contacts of an electrical wiring system having a plurality of contacts forming an electric network, comprising:a reference data storage means for storing reference data used as references in testing the connected states, a reading means for reading the connected states of the electrical wiring system to be compared with the reference data as test data from the contacts, and a discriminating means for discriminating the connected states of the electrical wiring system by comparing the test data read by the reading means with the reference data stored in the reference data storage means, wherein, based on the reference data in which the contacts are divided into a plurality of groups insulated from each other, the discriminating means first discriminates insulated states of the respective contacts among the respective groups and then discriminates in the respective groups if the insulated states of the respective groups are judged to be satisfactory, and wherein the number of the contacts included in each group is set using a square root of a total number of the contacts as a target value.
