綜合測試的目的是保證產(chǎn)品其本性能的一項測試試驗。耐壓測試的目的是為了防止產(chǎn)品在正常或不使用條件下發(fā)生漏電、電擊、火災(zāi)等事故危及消費(fèi)者的生命財產(chǎn)安全而采取的一項安全測試試驗。耐壓儀器在使用過程中必須墊絕緣膠皮，測試人員測試時，所在座位底板必須要墊絕緣膠皮。測試人員測試時，必須戴絕緣手套。測試時嚴(yán)禁接觸治具導(dǎo)電體，接觸高壓會對人體造成損傷。 </p> <p> 綜合測試儀日常維護(hù)注意事項： </p> <p> 1.為保證測試精確測試,開機(jī)預(yù)熱時間應(yīng)不少于15分鐘。 </p> <p> 2.請勿頻繁開關(guān)儀器,以引起內(nèi)部數(shù)據(jù)混亂,造成測試不準(zhǔn)確。 </p> <p> 3.不可帶電插撥測試連接線。 </p> <p> 4.遠(yuǎn)離磁場。 </p> <p>
