## Description

Southwire 40116N AC非接触電圧 (NCV) ペンテスターをツールバッグに追加する価値のあるものにします。 電気工事を行うときはいつでも使用して、電圧が存在する場所を特定します。 電線、照明スイッチ、遮断器、コンセント、照明器具の電圧を検出します。 Onボタンを押すと、検出チップが緑色に点灯します。 テスト対象の電線またはデバイスの近くに検出器チップを移動します。 電圧が検出されると、検出チップが緑から赤に変化し、点滅し始めます。 NCVも大音量でビープ音を鳴らします。 40116N はコンセントに直接挿入して動作確認することもできます。 Southwire 非接触電圧検出器はすべて、焦点を合わせたLED懐中電灯が内蔵されているため、暗い部分を照らすことができます。 自動電源オフ機能により、バッテリーの電力を節約できます。 さらに安全機能として、40116N はバッテリーの状態を定期的にチェックする低バッテリーセルフテストを実施しています。 バッテリー電圧が低くなりすぎると、セルフテスト回路はバッテリーを交換するまで非接触電圧検出器をオフにします。 40116NはUL規格取得済み。 不正開封防止(TR)コンセントには使用できません。
