Patent ID: 7975557

Claim:
A multiple testing system comprising: a plurality of testing units which are disposed independently and each have a loading mechanism applying a desired load quantity on a test body, and a detector detecting a load quantity applied on the test body; a single information processing device which includes a feedback control and, by multitasking control and with respect to the plurality of testing units, carries out test processing which includes: feedback control processing for, on the basis of the load quantity detected by the detector, controlling the loading mechanism such that the detected load quantity becomes a predetermined target value; control processing at an abnormal situation when at least one of an abnormality of the test body, an abnormality of a testing unit of the plurality of testing units, or an abnormality of a power source of the loading mechanism, is detected; and interface processing with an operator, wherein each of the plurality of test units is associated with a predetermined target value, and the single information processing device controls the predetermined target value of each of the plurality of testing units independently; and means for carrying out a constant value control, in the control processing at an abnormal situation when an abnormality of the test body of one of the testing units is detected, by changing the target value with respect to the one of the testing units to a predetermined constant value while the operation of the other testing units continues as is.
