數字兆歐表丈量電纜絕緣電阻方式

         數字6兆歐表有多個連接線(xian)柱：一些為“L"，一些為“E"，另有一些為“G"(深層)。仗(zhang)量(liang)電(dian)(dian)(dian)(dian)量(liang)錢路圖或光照錢路圖的(de)(de)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)耐壓電(dian)(dian)(dian)(dian)阻(zu)(zu)電(dian)(dian)(dian)(dian)容時(shi)“L"接被測錢路圖上，“E"接地(di)保護(hu)線(xian)。仗(zhang)量(liang)通(tong)信(xin)電(dian)(dian)(dian)(dian)線(xian)的(de)(de)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)耐壓電(dian)(dian)(dian)(dian)阻(zu)(zu)電(dian)(dian)(dian)(dian)容時(shi)，為使(shi)仗(zhang)量(liang)工(gong)作成(cheng)效切確，消弭線(xian)芯電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)耐壓電(dian)(dian)(dian)(dian)阻(zu)(zu)層形象(xiang)泄電(dian)(dian)(dian)(dian)所導至的(de)(de)仗(zhang)量(liang)誤差率，還(huan)應(ying)將“G"接完通(tong)信(xin)電(dian)(dian)(dian)(dian)線(xian)的(de)(de)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)耐壓電(dian)(dian)(dian)(dian)阻(zu)(zu)書本上。

　　在精確測量時(shi)要側重于如下幾點知識：

　　1、勘界電(dian)(dian)(dian)準(zhun)備(bei)(bei)的接地電(dian)(dian)(dian)阻器(qi)，一(yi)定(ding)要先(xian)封控電(dian)(dian)(dian)源模塊，遇(yu)上有電(dian)(dian)(dian)解(jie)電(dian)(dian)(dian)容脾(pi)氣的準(zhun)備(bei)(bei)，比擬電(dian)(dian)(dian)力電(dian)(dian)(dian)纜(lan)，新線(xian)路一(yi)定(ding)要*行電(dian)(dian)(dian)流。

　　2、數字9兆(zhao)歐表表運(yun)用時，須要平(ping)放。

　　3、自然數兆(zhao)歐(ou)表在進行以后要先運轉(zhuan)幾次，來(lai)看(kan)看(kan)游(you)標(biao)并不在非(fei)常(chang)大(da)處的實力地(di)位，然后再將“L"和“E"兩個人接(jie)線頭(tou)柱(zhu)虛接(jie)，一點一點地(di)運轉(zhuan)兆(zhao)歐(ou)表手柄，檢測游(you)標(biao)并不在“零(ling)"處。

　　4、數(shu)字9兆歐(ou)表引線不得不隔絕杰(jie)出貢(gong)獻，幾根線無(wu)需絞在開始(shi)。

　　5、金額(e)兆歐表關(guan)閉程序測量時，需要(yao)以移動1份鐘后的讀(du)數(shu)起算。

　　6、在側量(liang)時(shi)，時(shi)應兆歐(ou)表(biao)轉(zhuan)(zhuan)數滿足120轉(zhuan)(zhuan)/分。

　　7、數字(zi)化兆(zhao)歐表的(de)量(liang)限會時常達(da)兩千多兆(zhao)歐，最少(shao)標尺刻度在1兆(zhao)歐玩弄，所以說不(bu)一適(shi)仗量(liang)100千歐以上的(de)電阻功率。
