PURPOSE:To provide an unmanned system by incorporating a program for measuring a secular change to measure, indicate and generate the secular change of machine itself and comparing it with the stored reference value to generate an alarm before failures occur. CONSTITUTION:A detecting value 7 sampling ON time width in every fixed period is stored from a calculation unit 8 in a memory 13 as the measuring value according to a program stored in the memory 13. Then, the stored measuring value is indicated on a display unit 9 and compared with the reference value of data in each section stored previously in the memory 13 by the calculation unit 8 to light an alarming lamp 11 from an output section 10 and indicate an alarm on the display unit 9. A list is sent to a printer 12 through the output section 10. Thus, the operation can be carried out while observing how much the machine is change is from the normal condition so that the machine can be corrected before it fails and an unmanned machine can be provided.
