●　倍(bei)壓筒(tong)底(di)(di)盤側面(mian)有（四）五芯(xin)插(cha)座(zuo)為聯接(jie)控制箱電纜之插(cha)座(zuo)，底(di)(di)盤側面(mian)有銅接(jie)線柱(zhu)為接(jie)地(di)端子作連(lian)接(jie)地(di)線用。
●　附(fu)帶的(de)(de)高壓屏蔽電(dian)流表為(wei)數顯微安表，表頂端上的(de)(de)插孔為(wei)連接被試品的(de)(de)線插孔，同時也作為(wei)電(dian)源(yuan)開關，不用時請(qing)拔掉插頭，就自動(dong)關閉(bi)電(dian)源(yuan)。換電(dian)池時請(qing)將(jiang)后(hou)蓋旋(xuan)(xuan)下，換好后(hou)請(qing)將(jiang)后(hou)蓋旋(xuan)(xuan)緊。

1、使用前(qian)準備
⑴ 　直(zhi)流發生器在使用前(qian)應(ying)檢查其完好性(xing),聯接電纜(lan)線不應(ying)有斷路(lu)和短路(lu)，設備(bei)無(wu)破裂等(deng)損壞。

⑵　將機箱、倍壓筒放置到(dao)合適的(de)安全的(de)位(wei)置，分別(bie)聯接(jie)好(hao)(hao)電(dian)源線(xian)(xian)、電(dian)纜線(xian)(xian)和接(jie)地(di)(di)線(xian)(xian)。保護接(jie)地(di)(di)線(xian)(xian)與工作接(jie)地(di)(di)線(xian)(xian)以及放電(dian)棒的(de)接(jie)地(di)(di)線(xian)(xian)均應單(dan)獨(du)接(jie)到(dao)試品(pin)的(de)地(di)(di)線(xian)(xian)上(即一點(dian)接(jie)地(di)(di))并確保接(jie)地(di)(di)良好(hao)(hao)。嚴禁各接(jie)地(di)(di)線(xian)(xian)相(xiang)互串聯使用(yong)，以免擊(ji)穿時地(di)(di)電(dian)位(wei)抬高形成反擊(ji)，損壞儀(yi)器。

⑶ 　檢查(cha)電源開關(guan)(guan)是(shi)否在(zai)關(guan)(guan)斷的(de)(de)位(wei)置(zhi)上(shang)，并檢查(cha)調壓(ya)電位(wei)器應在(zai)零(ling)位(wei)上(shang),過電壓(ya)保護整(zheng)定撥盤開關(guan)(guan)設置(zhi)在(zai)適(shi)當的(de)(de)位(wei)置(zhi)上(shang)，一(yi)般為1.10～1.20倍測試電壓(ya)值。

2、空載升壓驗證過(guo)電壓保護整定(ding)值(zhi)
