Isisombululo kwi iqondo eliphezulu lobushushu ibhokisi-uhlobo ukumelana eziko hayi ukufudumeza

① Umbane wombane uqhelekile, umlawuli usebenza ngokwesiqhelo, kwaye i-ammeter ayinaso isibonisi. Kungenzeka ukuba ucingo lwesithando sombane lwebhokisi lobushushu obuphezulu-uhlobo lokumelana nesithando somlilo luvulekile, olunokuthi luhlolwe nge-multimeter kwaye lutshintshwe ngocingo lwesithando sombane lwenkcazo efanayo.

②Umbane wombane uqhelekile, kwaye umlawuli akanakusebenza. Ukutshintsha, i-fuse kunye nohambo lokuhamba komnyango wesithando somlilo kunokuhlolwa kwaye kulungiswe ngaphakathi komlawuli. Ukuba umnyango wesithando somlilo wombane awuvaliwe kwaye umlawuli akakwazi ukusebenza, kufuneka alungiswe ngokwendlela yokulungisa ukungaphumeleli komlawuli.

③Ukungaphumeleli konikezelo lwamandla: lusebenza ngokuqhelekileyo xa lungaxhunywanga kwiziko lombane, kodwa alusebenzi ngokuqhelekileyo xa luqhagamshelwe kwiziko lombane, kwaye kukho isandi esicofayo esiqhubekayo kwisilawuli. Isizathu kukuba i-voltage drop of the power supply circuit of the high heat box-type resistant furnace inkulu kakhulu, okanye i-socket kunye ne-control switch ayidibanisi kakuhle, enokutshintshwa okanye ifakwe endaweni.
