P\u0159ed prac\u00ed na jak\u00e9mkoli elektrick\u00e9m za\u0159\u00edzen\u00ed je z\u00e1sadn\u00ed zajistit svou bezpe\u010dnost. Nespr\u00e1vn\u011b ozna\u010den\u00e9 jisti\u010de nebo vz\u00e1jemn\u011b propojen\u00e9 obvody mohou p\u0159edstavovat riziko \u00farazu elektrick\u00fdm proudem. Pokud si nejste jisti, vypn\u011bte hlavn\u00ed jisti\u010d. T\u00edm v\u0161ak vypnete proud v cel\u00e9m dom\u011b. Chcete-li m\u00edt jistotu, zavolejte kvalifikovan\u00e9ho elektrik\u00e1\u0159e, pokud m\u00e1te jak\u00e9koli obavy ohledn\u011b pr\u00e1ce s elekt\u0159inou v dom\u00e1cnosti.<\/p>\n\n

Kdy\u017e zap\u00edn\u00e1te a vyp\u00edn\u00e1te jisti\u010de, \u017e\u00e1rovka indikuje jisti\u010d, kter\u00fd ovl\u00e1d\u00e1 z\u00e1suvku, kdy\u017e zhasne. Tato technika je ide\u00e1ln\u00ed pro mapov\u00e1n\u00ed jisti\u010d\u016f a zji\u0161\u0165ov\u00e1n\u00ed, zda je z\u00e1suvka nap\u00e1jena.<\/p>\n\n

Zku\u0161ebn\u00ed p\u0159\u00edstroje nap\u011bt\u00ed jsou levn\u00e1 a snadno pou\u017eiteln\u00e1 za\u0159\u00edzen\u00ed, kter\u00e1 detekuj\u00ed elektrick\u00fd proud bez dotyku hol\u00fdch vodi\u010d\u016f. Jak pou\u017e\u00edvat zkou\u0161e\u010dku nap\u011bt\u00ed:<\/p>\n\n

    \n
  1. Vlo\u017ete do testeru nov\u00e9 baterie a zajist\u011bte spr\u00e1vnou polaritu.<\/li>\n
  2. Zapn\u011bte tester a otestujte jej na zn\u00e1m\u00e9 \u017eiv\u00e9 z\u00e1suvce.<\/li>\n
  3. Dr\u017ete hrot testeru asi centimetr od vodi\u010de nebo z\u00e1suvky, abyste detekovali proud.<\/li>\n<\/ol>\n\n

    Zku\u0161ebn\u00ed p\u0159\u00edstroje nap\u011bt\u00ed indikuj\u00ed p\u0159\u00edtomnost proudu, ale neposkytuj\u00ed m\u011b\u0159en\u00ed nap\u011bt\u00ed. Mohou tak\u00e9 produkovat fale\u0161n\u011b pozitivn\u00ed nebo fale\u0161n\u011b negativn\u00ed v\u00fdsledky, proto tester p\u0159ed pou\u017eit\u00edm v\u017edy otestujte.<\/p>\n\n

    Testov\u00e1n\u00ed zkou\u0161e\u010dky nap\u011bt\u00ed<\/h2>\n\n

    Abyste zajistili p\u0159esnost sv\u00e9 zkou\u0161e\u010dky nap\u011bt\u00ed, otestujte ji na zn\u00e1m\u00e9m \u017eiv\u00e9m okruhu:<\/p>\n\n

      \n
    1. Identifikujte \u017eivou z\u00e1suvku, kter\u00e1 nap\u00e1j\u00ed za\u0159\u00edzen\u00ed.<\/li>\n
    2. Vlo\u017ete konec zkou\u0161e\u010dky nap\u011bt\u00ed do obou slot\u016f z\u00e1suvky.<\/li>\n
    3. Blikaj\u00edc\u00ed sv\u011btlo nebo p\u00edpnut\u00ed indikuje p\u0159\u00edtomnost \u017eiv\u00e9ho proudu.<\/li>\n<\/ol>\n\n

      Otestujte v\u0161echny vodi\u010de uvnit\u0159 z\u00e1suvky, jakmile je otev\u0159ena pro pr\u00e1ci, i kdy\u017e tester zpo\u010d\u00e1tku nezjistil proud.<\/p>\n\n

      Testov\u00e1n\u00ed elektrick\u00fdch kabel\u016f<\/h2>\n\n

      Zku\u0161ebn\u00ed p\u0159\u00edstroje nap\u011bt\u00ed lze tak\u00e9 pou\u017e\u00edt k testov\u00e1n\u00ed elektrick\u00fdch kabel\u016f na p\u0159\u00edtomnost proudu. Dr\u017ete hrot testeru na boku kabelu a dot\u00fdkejte se kolem n\u011bj. Tester indikuje \u017eiv\u00fd proud, kdy\u017e je proti kladn\u00e9mu (hork\u00e9mu) vodi\u010di.<\/p>\n\n
