Abstract

PURPOSE:To facilitate an easy study for the trouble factors with a simple constitution when a trouble arises, by giving the proper weighing to the digital signal corresponding to the operations of several apparatus to be recorded and then recording the output converted into the analog signal. CONSTITUTION:The working condition (on/off contact) of the electric apparatus X1-X5 such as a contact device or the like to which the working condition is recorded is sent to the input circuit 11 to be replaced with ''1'' and ''0'' when the contact is on and off respectively. This digital signal receives the weighing in such way that 2<0> and 2<1>... are given to the signals of X1 and X2 respectively to be then sent to the D/A converter 12. Then the output analog signal is recorded to the recorder 13. For the comparison and study between the normal and abnormal states, the comparison is carried out with the recorded analog patterns. And the factors of a trouble are detected by using the reference pattern.
