Summary:PROBLEM TO BE SOLVED: To provide a plug checking device capable of easily checking a voltage plug or a current plug.SOLUTION: A voltage plug P1 is checked by: selecting one terminal of a PTT plug housing part 10 by a PTT rotary switch part 20; connecting the selected terminal to one measuring terminal of a tester part 60; and connecting the remaining terminals, which are in electric contact with one another, to the other measuring terminal of the tester part 60. A current plug P2 is checked by: selecting one of terminals of a CTT plug housing part 30 that are in contact with a short circuit side, by a CTT rotary switch part 40; connecting the selected terminal to one measuring terminal of the tester part 60; and connecting the remaining terminals in contact with the short circuit side, which are in electric contact with one another through respective resistors, to the other measuring terminal of the tester part 60.SELECTED DRAWING: Figure 1 【課題】 電圧プラグまたは電流プラグを容易にチェック可能なプラグチェック装置を提供すること。【解決手段】 電圧プラグＰ１のチェック時には、ＰＴＴ用ロータリースイッチ部２０により、ＰＴＴ用プラグ収納部１０の１つの端子を選択し、該選択した端子をテスター部６０の一方の測定端子に接続すると共に、残りの端子を電気的に接触させた状態で、これらのすべての端子をテスター部６０の他方の測定端子に接続してチェックを行う。電流プラグＰ２のチェック時には、ＣＴＴ用ロータリースイッチ部４０により、ＣＴＴ用プラグ収納部３０が持つ各端子で短絡側と接触している端子の中の１つを選択し、該選択した端子をテスター部６０の一方の測定端子に接続すると共に、短絡側と接触している端子の残りの端子を、抵抗を介在して電気的に接触させた状態で、これらのすべての端子をテスター部６０の他方の測定端子に接続してチェックを行う。【選択図】 図１
