PROBLEM TO BE SOLVED: To readily test a plurality of switchboards at the same time by reducing the number of testing devices. SOLUTION: This relay tester comprises means 24 that calculates an input quantity of testing from an arbitrary input quantity of testing inputted from the outside and setting data of a relay to be tested, converts the calculated result to a digital signal and outputs it to a device 4 to be tested, a test controlling section 2 consisting of means 26, 27 that determine good or bad of the testing result of the relay inputted from the device 4 to store and indicate it and an interface section 3 consisting of a means that outputs the digital signal inputted from the test controlling section 2 to the relay and a means that inputs the testing result of the relay to the test controlling section 2. |
