3)正(zheng)(zheng)確使(shi)用:機(ji)械調(diao)零(把指(zhi)(zhi)針調(diao)到零刻度(du))并聯(lian)(lian)(lian)(電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)(ya)(ya)(ya)(ya)(ya)表(biao)(biao)(biao)內(nei)阻很大(da),串聯(lian)(lian)(lian)在(zai)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)路(lu)中會造成斷路(lu)。)正(zheng)(zheng)進負(fu)出(使(shi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)(liu)(liu)從正(zheng)(zheng)極(ji)接(jie)(jie)入(ru)流(liu)(liu)(liu)(liu)進,從負(fu)極(ji)接(jie)(jie)入(ru)流(liu)(liu)(liu)(liu)出。)量(liang)程(cheng)(被測(ce)(ce)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)(ya)(ya)(ya)(ya)(ya)不(bu)能(neng)超過(guo)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)(ya)(ya)(ya)(ya)(ya)表(biao)(biao)(biao)的(de)(de)(de)(de)(de)量(liang)程(cheng),注意(yi):如果(guo)不(bu)能(neng)估(gu)計(ji)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)路(lu)上(shang)(shang)的(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)(ya)(ya)(ya)(ya)(ya),先用大(da)的(de)(de)(de)(de)(de)量(liang)程(cheng)試觸,粗略測(ce)(ce)得(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)(ya)(ya)(ya)(ya)(ya)后,再用適合(he)的(de)(de)(de)(de)(de)量(liang)程(cheng)。這(zhe)樣可(ke)以防止電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)(ya)(ya)(ya)(ya)(ya)過(guo)大(da)而打(da)彎指(zhi)(zhi)針。)
