Hoob II thiab Chav Kawm 2 yog ob lub ntsiab kev nyab xeeb. Txawm li cas los xij, rau ntau tus pib ntawm LED tsav lub zog, Chav Kawm II thiab Chav Kawm 2 muaj qhov sib txawv ntawm lub tswv yim kev nyab xeeb vim tias lawv hais tau zoo ib yam. Ob lub tswv yim los ntawm ob lub qauv sib txawv:
Hoob II tswvyim
Hoob II feem ntau yog xav txog hom rwb thaiv tsev siv nyob rau hauv kev tiv thaiv hluav taws xob ntawm qhov khoom. Nws yog muab los ntawm IEC txheej txheem qauv. Cov lus piav qhia yooj yim yog raws li hauv qab no: Cov qauv kev nyab xeeb ntawm cov teeb tau muab faib ua plaub pawg: Chav kawm I, Chav Kawm I, Chav Kawm II thiab Chav Kawm III.
Chav 0 teeb
Relying ntawm cov rwb thaiv tsev yooj yim raws li kev tiv thaiv kev tiv thaiv hluav taws xob - tsuas yog los ntawm cov hlau hluav taws xob. Thaum muaj teeb meem thaiv qhov tsis ua haujlwm yooj yim (xaim tawg: tawg tawv nqaij thaum hla dhau txoj kab), nws yuav ua rau muaj hluav taws xob thiab hluav taws kub nyhiab. Kev tiv thaiv hluav taws xob tiv thaiv hluav taws xob tau vam khom ib puag ncig.
Chav Kawm Kuv Teeb
Cov kev tiv thaiv tiv thaiv hluav taws xob tsis yog tsuas yog cuam tshuam rau cov rwb thaiv tsev yooj yim, tab sis kuj suav nrog kev ntsuas kev nyab xeeb ntxiv, uas yog, txuas qhov chaw nkag mus rau qhov chaw tiv thaiv kab hluav taws xob nyob rau hauv cov kab txuas, kom thiaj li nkag mus rau qhov chaw tau khoom tsis raug them thaum muaj qhov tsis ua tiav ntawm qhov rwb thaiv tsev yooj yim (Chav 0 teeb + av hlau).
Chav Kawm Teeb II
Cov Ntsiab Lus ntawm Class II teeb txawb:
Kev tiv thaiv hluav taws xob tsis tsuas yog cuam tshuam rau cov rwb thaiv tsev yooj yim, tab sis kuj muaj kev tiv thaiv kev nyab xeeb ntxiv, xws li kev tiv thaiv ob chav lossis thaiv kom tsis muaj zog, tab sis tsis muaj qhov thaiv lossis tiv thaiv nyob ntawm cov teeb meem kev teeb tsa.
