Abstract

PURPOSE:To collect information efficiently with unattended method, by adding the function of discrimination for necessary/unnecessary monitor information. CONSTITUTION:When a start control signal is detected through a start control lead 6, the control section 2 reads in the presence of a potential of a measuring lead 5 through an interface section 1, it is stored with ''0''9''1'' display in a determined memory area in a storage section 3 and the storage area is advanced. Next, the presence of an output control signal is retrieved through an output control lead 7, and if the output control signal is not detected, the designated time to enter the next reading operation is measured with a clock pulse. This is repeated for prescribed times, and if the output control signal is not detected during it, the control section 2 erases misinformation as unnecessary information. When an output control signal is detected, the control section 2 judges it as the production in abnormal operation, the information stored in the storage section 3 is transferred to a recording and display section 4 and recording and display are made.
