a.脈(mo)沖法測(ce)試時，注意要甩(shuai)掉局內所(suo)有(you)設備，在zui外線上進行測(ce)量。
b.使用閃絡法測試時，必(bi)須(xu)將(jiang)觸發工作方(fang)式開關置于(yu)“閃絡”位置。
c.在使用直閃(shan)法(fa)或沖閃(shan)法(fa)測試時，要注意人(ren)身安(an)全及(ji)設備安(an)全。必須接好地(di)線。
d.在閃絡法測(ce)試結(jie)束后，切斷電(dian)(dian)(dian)源，拆(chai)除本儀器與高壓測(ce)試裝置的連接線，再對(dui)高壓電(dian)(dian)(dian)容器和(he)電(dian)(dian)(dian)纜的所貯電(dian)(dian)(dian)荷進行放(fang)(fang)電(dian)(dian)(dian)。放(fang)(fang)電(dian)(dian)(dian)時，應先加限(xian)流(liu)電(dian)(dian)(dian)阻R限(xian)制(zhi)放(fang)(fang)電(dian)(dian)(dian)電(dian)(dian)(dian)流(liu)以使電(dian)(dian)(dian)流(liu)緩慢放(fang)(fang)電(dian)(dian)(dian)，待電(dian)(dian)(dian)容器上電(dian)(dian)(dian)壓降低后，再直(zhi)接對(dui)地(di)放(fang)(fang)電(dian)(dian)(dian)電(dian)(dian)(dian)路中電(dian)(dian)(dian)阻為零(ling)，瞬間放(fang)(fang)電(dian)(dian)(dian)電(dian)(dian)(dian)流(liu)可高達(da)幾百安培，將發生嚴重的設備或人(ren)身(shen)事故。
