Document Type and Number:
Japanese Patent JP6284971
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a tester and method for checking wire connection, used in an outlet having a non-energization state and capable of properly determining the wiring correction of the outlet.SOLUTION: A tester 100 for checking wire connection comprises: a power supply unit 3 having two DC power supplies 1 and 2 having the same voltage and connected in series; an oscillator 10 having connection parts 11, 12 and 13 for connecting electric wires from both sides and middle of the power supply unit 3 to respective terminals L, N and E of a single-phase tree wire system in a distribution board; a failure content formation circuit 23 for detecting a DC voltage applied among the terminals of an outlet 40 to be determined; a specified voltage combination determination circuit 24 for comparing the combination of the DC voltages among the detected terminals with the combination of specified voltages predetermined according to failure contents to determine the failure contents; and a tester body 20 having a display 26 for displaying the determined failure contents.SELECTED DRAWING: Figure 1
