Abstract
A system abnormality determining method comprises the steps of transmitting fake abnormal information representing an abnormal condition of the target instrument from the target instrument to a condition determination device via a network during a test operation of the target instrument instead of condition information, determining if the condition determination device can determine the target instrument as being abnormal based on the fake abnormal information, and operating the target instrument in a normal operation condition when the condition determination device can determine the target instrument as being abnormal.
