數字接(jie)地電(dian)阻測試(shi)儀(yi)

產品簡介

鉗形接(jie)地(di)電(dian)(dian)(dian)阻測(ce)試(shi)儀(yi),接(jie)地(di)電(dian)(dian)(dian)阻表,接(jie)地(di)表用于電(dian)(dian)(dian)力、通信(xin)、鐵路及工礦(kuang)企業等部門各種裝(zhuang)置接(jie)地(di)電(dian)(dian)(dian)阻值的測(ce)量。同時，數字接(jie)地(di)電(dian)(dian)(dian)阻測(ce)試(shi)儀(yi)可測(ce)量土壤電(dian)(dian)(dian)阻率及地(di)電(dian)(dian)(dian)壓。

摒棄傳統的人工手搖發電(dian)工作方式(shi)，接地電(dian)阻測(ce)試儀采用(yong)*的中大規模集成電(dian)路， 應用(yong)DC/AC變換(huan)技術將三端(duan)鈕、四端(duan)鈕測(ce)量(liang)方式(shi)合并為一種機型的新(xin)型接地電(dian)阻測(ce)量(liang)儀。

產品特征

1、結構上采用(yong)高強度鋁合(he)金作為(wei)機(ji)殼(ke)，電(dian)路上為(wei)防止工頻、射頻干擾采用(yong)鎖相環(huan)同步跟(gen)蹤檢波方(fang)式(shi)并配以開(kai)關電(dian)容濾(lv)波器使(shi)儀(yi)表有較好(hao)的抗干擾能(neng)力

2、采用DC/AC變(bian)換技術將直流(liu)變(bian)為交流(liu)的低頻恒定電流(liu)以(yi)便于測量(liang)

3、允(yun)許輔(fu)助接地(di)電阻在0～1.8KΩ(RC)，0～40KΩ(RP)之間變化，不致于(yu)影響測量結(jie)果 

4、本(ben)接地電(dian)(dian)(dian)(dian)(dian)阻(zu)表不(bu)需(xu)人工調節平衡，3(1/2)位(wei)LCD顯(xian)示，除測地電(dian)(dian)(dian)(dian)(dian)阻(zu)外，還可測低電(dian)(dian)(dian)(dian)(dian)阻(zu)導體電(dian)(dian)(dian)(dian)(dian)阻(zu)、土壤電(dian)(dian)(dian)(dian)(dian)阻(zu)率以(yi)及交流地電(dian)(dian)(dian)(dian)(dian)壓。如若測試回(hui)路不(bu)通表頭顯(xian)示“1”代表溢(yi)出(chu)，

符合常規測(ce)量習(xi)慣
