CS9950SASCSDS程控接地阻抗測試儀產品介紹

CS9950DS型程控(kong)接地電(dian)(dian)(dian)阻(zu)測(ce)(ce)試(shi)儀,它們采用微電(dian)(dian)(dian)腦控(kong)制(zhi)(zhi)器控(kong)制(zhi)(zhi)輸(shu)出(chu)(chu)電(dian)(dian)(dian)流(liu)(liu)的(de)(de)(de)(de)(de)大小(xiao)和輸(shu)出(chu)(chu)電(dian)(dian)(dian)流(liu)(liu)的(de)(de)(de)(de)(de)頻(pin)率；測(ce)(ce)試(shi)儀電(dian)(dian)(dian)流(liu)(liu)輸(shu)出(chu)(chu)為恒流(liu)(liu)源輸(shu)出(chu)(chu)，即在測(ce)(ce)試(shi)儀的(de)(de)(de)(de)(de)測(ce)(ce)試(shi)范圍內，輸(shu)出(chu)(chu)電(dian)(dian)(dian)流(liu)(liu)的(de)(de)(de)(de)(de)大小(xiao)不隨(sui)外接負載(zai)阻(zu)值(zhi)的(de)(de)(de)(de)(de)變化(hua)(hua)而(er)變化(hua)(hua)，輸(shu)出(chu)(chu)電(dian)(dian)(dian)流(liu)(liu)值(zhi)為設置電(dian)(dian)(dian)流(liu)(liu)值(zhi)；具(ju)有開路報(bao)警功能(neng)，配備PLC所需(xu)的(de)(de)(de)(de)(de)信號(hao)輸(shu)入(ru)、輸(shu)出(chu)(chu)接口，可方便的(de)(de)(de)(de)(de)與PLC組成(cheng)綜(zong)合(he)測(ce)(ce)試(shi)系統，亦(yi)可選配RS232接口，能(neng)夠(gou)準確地測(ce)(ce)量各種電(dian)(dian)(dian)機、電(dian)(dian)(dian)器、儀器儀表、家用電(dian)(dian)(dian)器等用電(dian)(dian)(dian)網(wang)供(gong)電(dian)(dian)(dian)的(de)(de)(de)(de)(de)電(dian)(dian)(dian)氣設備外殼易觸(chu)及金屬部(bu)件與其(qi)保護接地端(duan)子之間的(de)(de)(de)(de)(de)電(dian)(dian)(dian)阻(zu)值(zhi)。

性能特點

●恒流(liu)輸出(chu)：輸出(chu)電(dian)流(liu)穩(wen)定率范圍在(zai)1%內(nei)，避(bi)免因(yin)輸入電(dian)源電(dian)壓不穩(wen)及負(fu)載變(bian)化而使輸出(chu)電(dian)壓變(bian)化，測量結果不準確。

●具有開(kai)路報警(jing)功能(neng)。

●采(cai)用四端(duan)法測量，消除(chu)接觸(chu)電阻的影響。

●可設置電(dian)阻偏移。

●具有(you)電阻上限(xian)、下(xia)限(xian)報警功能，避免因測試線開路對被測時件(jian)造成誤判；

●設置參數具有掉電記憶功能。

●測(ce)試參數具有(you)保持功能。

●可預先設置(zhi)保存測試參數(shu)：可設置(zhi)30個文件，每個文件可設置(zhi)99個測試步(bu)。

●具(ju)有(you)鍵(jian)盤鎖，保護測試參數不(bu)被操作人員修改。

●前面板軟件校(xiao)準(zhun)，不用打開即可進(jin)行參數校(xiao)準(zhun)。

●標(biao)配PLC接口，選(xuan)配RS232C、RS485、USB、GPIB接口。
