Abstract

PURPOSE: To readily measure the characteristics of a load circuit including a reactance component as a contact load by employing a circuit using at least one of a capacitive and inductive elements as the load circuit of a relay contact.
CONSTITUTION: When a switch 8 is changed over a load circuit 6 side by a change signal S1, the circuit 6 is connected to predetermined load circuit always containing at least one of the capacitor and a coil by a control signal S3 to thereby cause the load circuit to be connected to a contact 5. A control circuit 9 produces N1 of pulses from a relay drive circuit 4 on the basis of a drive circuit information S5 in this state to energize the coil 3 N1 times intermittently to thereby open and close the contact 5 connected with predetermined load circuit N1 times. Then, the switch 8 is again changed over a measuring unit 7 side by the change signal S1. These series of operations are alternatively repeated predetermined times to thus measure the relay life.
