5、 經檢查(cha)接線確認無誤后，蓋上控制器(qi)外(wai)殼(ke)。將溫(wen)(wen)(wen)(wen)度指示(shi)(shi)(shi)儀的(de)設定(ding)指針調整(zheng)至所(suo)需要(yao)的(de)工作溫(wen)(wen)(wen)(wen)度，然后接通電(dian)(dian)(dian)(dian)源(yuan)。打開電(dian)(dian)(dian)(dian)源(yuan)開關(guan)，此(ci)時(shi)溫(wen)(wen)(wen)(wen)度指示(shi)(shi)(shi)儀表(biao)(biao)(biao)上的(de)綠燈(deng)即亮，繼電(dian)(dian)(dian)(dian)器(qi)開始工作，電(dian)(dian)(dian)(dian)爐通電(dian)(dian)(dian)(dian)，電(dian)(dian)(dian)(dian)流表(biao)(biao)(biao)即有電(dian)(dian)(dian)(dian)流顯(xian)示(shi)(shi)(shi)。隨著電(dian)(dian)(dian)(dian)爐內部溫(wen)(wen)(wen)(wen)度的(de)升高，溫(wen)(wen)(wen)(wen)度指示(shi)(shi)(shi)儀表(biao)(biao)(biao)指針也(ye)逐漸上升，此(ci)現象表(biao)(biao)(biao)明系統(tong)工作正常。電(dian)(dian)(dian)(dian)爐的(de)升溫(wen)(wen)(wen)(wen)、定(ding)溫(wen)(wen)(wen)(wen)分(fen)別(bie)以溫(wen)(wen)(wen)(wen)度指示(shi)(shi)(shi)儀的(de)紅(hong)綠燈(deng)指示(shi)(shi)(shi)，綠燈(deng)表(biao)(biao)(biao)示(shi)(shi)(shi)升溫(wen)(wen)(wen)(wen)，紅(hong)燈(deng)表(biao)(biao)(biao)示(shi)(shi)(shi)定(ding)溫(wen)(wen)(wen)(wen)。
