PROBLEM TO BE SOLVED: To provide a tester for achieving enhancement of workability in the test of a remote transmission control apparatus, and shortening of the operation time.SOLUTION: A tester 1 includes a first light bulb 40 and a second light bulb 42 connected in parallel with a power supply, outlets and terminals 44, 46 for first and second arbitrary loads, a first uninterruptible terminal 26 for single-phase two wires for connection with a remote transmission control apparatus 100 and a second uninterruptible terminal 30 for single phase three wires, a first load main SW36 for connection with the first uninterruptible terminal 26, and a second load main SW38 for connection with the second uninterruptible terminal 30. The terminals 26 and SW36 are connected in series with the light bulb 40 and terminal 44. The terminal 30 has a terminal pair of the primary terminals 30a, 30c and secondary terminals 30b, 30d for connection with the apparatus 100, so that the current of two phases of the single-phase three wires flows to the apparatus 100. The terminal 30d is connected with the SW38, which is connected in series with the light bulb 42 and terminal 46, and the terminal 30b is connected with the SW36.SELECTED DRAWING: Figure 3 |
