Kev siv yooj yim ntawm multimeter - ntsuas tam sim no
Thaum ntsuas DC tam sim no, thawj zaug ntxig cov xim dub coj mus rau hauv qhov chaw nres nkoj COM pej xeem, thiab kuaj liab coj mus rau 10A lossis mA jack (ceeb toom: yog tias tam sim no ntau dua 400mA, xaiv
10A jack, xaiv mA jack yog tias nws tsawg dua 400mA); ces tig lub pob qhov rooj mus rau A- lossis mA- lossis uA- (Ceeb toom: Yog tias qhov ntsuas DC tam sim no tsis paub, ua ntej tig lub pob qhov rooj rau A-); Thaum kawg Txuas cov digital multimeter hauv series nrog lub voj voog hauv kev sim. Nyob rau lub sijhawm no, nws yuav tsum tau muab sau tseg tias qhov kev xeem liab thiab xim dub ntawm cov digital multimeter yuav tsum sib haum mus rau qhov muaj peev xwm siab thiab tsis tshua muaj peev xwm ntawm Circuit Court nyob rau hauv kev ntsuam xyuas feem.
Txoj kev ntsuas ntawm AC tam sim no yeej zoo ib yam li DC tam sim no, qhov sib txawv yog tias lub pob qhov rooj yuav tsum tig mus rau A ~ lossis mA ~ lossis uA ~, thiab qhov kev xeem ua tsis muaj polarity.
