CS9950CX程控接地電阻測試儀主要特色

◆恒流輸(shu)(shu)(shu)出(chu)(chu)：輸(shu)(shu)(shu)出(chu)(chu)電流穩定(ding)率范圍在(zai)1%內，避(bi)免因輸(shu)(shu)(shu)入(ru)電源(yuan)電壓(ya)不穩及負載變化而使(shi)輸(shu)(shu)(shu)出(chu)(chu)電壓(ya)變化，測量結果(guo)不準確。

◆具有(you)開路報警(jing)功(gong)能(neng)。

◆采用四端法測量，消除(chu)接觸電阻(zu)的(de)影響。

◆可(ke)設(she)置(zhi)電阻偏移(yi)。

◆具有電(dian)阻上限(xian)、下限(xian)報警功能，避免因(yin)測試線開路對被(bei)測時件造(zao)成誤(wu)判；

◆設置(zhi)參數具有掉電記憶功(gong)能。

◆測試參(can)數具(ju)有保持功能。

◆可(ke)預先設(she)置保存測試(shi)參數：可(ke)設(she)置30個文件，每個文件可(ke)設(she)置99個測試(shi)步。

CS9950CX程控接地電阻測試儀產品介紹

 CS9950CX型(xing)程控(kong)(kong)接(jie)(jie)地(di)電(dian)(dian)(dian)(dian)阻(zu)測(ce)試(shi)儀(yi),它們采用(yong)微電(dian)(dian)(dian)(dian)腦控(kong)(kong)制器(qi)(qi)控(kong)(kong)制輸(shu)(shu)出(chu)(chu)(chu)電(dian)(dian)(dian)(dian)流(liu)(liu)的大小和輸(shu)(shu)出(chu)(chu)(chu)電(dian)(dian)(dian)(dian)流(liu)(liu)的頻(pin)率；測(ce)試(shi)儀(yi)電(dian)(dian)(dian)(dian)流(liu)(liu)輸(shu)(shu)出(chu)(chu)(chu)為恒流(liu)(liu)源輸(shu)(shu)出(chu)(chu)(chu)，即(ji)在測(ce)試(shi)儀(yi)的測(ce)試(shi)范(fan)圍內，輸(shu)(shu)出(chu)(chu)(chu)電(dian)(dian)(dian)(dian)流(liu)(liu)的大小不隨外接(jie)(jie)負載阻(zu)值的變化而變化，輸(shu)(shu)出(chu)(chu)(chu)電(dian)(dian)(dian)(dian)流(liu)(liu)值為設(she)(she)置(zhi)電(dian)(dian)(dian)(dian)流(liu)(liu)值；具有開路報警功能，配備(bei)PLC所需的信號輸(shu)(shu)入、輸(shu)(shu)出(chu)(chu)(chu)接(jie)(jie)口(kou)(kou)，可方便的與(yu)PLC組成綜合測(ce)試(shi)系統，亦(yi)可選配RS232接(jie)(jie)口(kou)(kou)，能夠(gou)準確(que)地(di)測(ce)量各種(zhong)電(dian)(dian)(dian)(dian)機、電(dian)(dian)(dian)(dian)器(qi)(qi)、儀(yi)器(qi)(qi)儀(yi)表、家用(yong)電(dian)(dian)(dian)(dian)器(qi)(qi)等用(yong)電(dian)(dian)(dian)(dian)網供電(dian)(dian)(dian)(dian)的電(dian)(dian)(dian)(dian)氣設(she)(she)備(bei)外殼易觸及金屬(shu)部件與(yu)其保護接(jie)(jie)地(di)端子之間的電(dian)(dian)(dian)(dian)阻(zu)值。

性能特點

◆恒流輸(shu)出：輸(shu)出電(dian)流穩定率范圍(wei)在1%內(nei)，避免因(yin)輸(shu)入電(dian)源電(dian)壓不穩及負載變化(hua)而使(shi)輸(shu)出電(dian)壓變化(hua)，測量結果不準確。

◆具有開(kai)路(lu)報警功能。

◆采(cai)用(yong)四(si)端法測量，消除接(jie)觸(chu)電阻的(de)影響。

◆可設置(zhi)電阻偏移。

◆具有電阻(zu)上限、下限報警功能，避免(mian)因測試(shi)線開路對被測時件造成誤(wu)判；

◆設置參數具有掉電記(ji)憶(yi)功能。

◆測試參數具有(you)保持功能。

◆可(ke)預先設(she)置(zhi)保存測試(shi)參數(shu)：可(ke)設(she)置(zhi)30個(ge)文件(jian)，每(mei)個(ge)文件(jian)可(ke)設(she)置(zhi)99個(ge)測試(shi)步。

◆具有鍵盤鎖，保護測試參數不(bu)被(bei)操(cao)作人員修改(gai)。

◆前面(mian)板軟(ruan)件校(xiao)準(zhun)，不(bu)用打開即可進行參數校(xiao)準(zhun)。

◆標配(pei)PLC接(jie)口，選(xuan)配(pei)RS232C、RS485、USB、GPIB接(jie)口。
