PURPOSE:To facilitate the rewriting of reference data corresponding to model changes or changes in the characteristic by memorizing data for automatic testing into a magnetic recorder (such as MT and FD). CONSTITUTION:An automatic tester 2A has an auxiliary memory device such as magnetic cassette tape 12 to memorize a reference value as criterion for the results of measurement. On the other hand, the operation part 3A comprises a measuring item selection switch 3A1, a measuring item setting switch 3A2 and the like and a display 3A5. In the operation, a microcomputer 5 transfers all of reference values stored in the magnetic cassette tape 12 to an RAM9 to execute a testing. The results of the measurement with a measuring control circuit 8 are stored into the RAM9 through an input unit 4 and then, outputted through an output unit 7 after a judgement on the quality thereof with the microcomputer 5. The alteration of the reference data can be performed easily by exchanging the auxiliary memory medium or rewriting the contents thereof only. |
