ZY9733型數(shu)字化臺式小電(dian)(dian)(dian)(dian)流(liu)電(dian)(dian)(dian)(dian)阻(zu)測(ce)試(shi)儀，適宜用(yong)檢測(ce)對(dui)電(dian)(dian)(dian)(dian)流(liu)有一定(ding)限(xian)制(zhi)要(yao)求的各類(lei)直流(liu)電(dian)(dian)(dian)(dian)阻(zu),如鉑熱(re)電(dian)(dian)(dian)(dian)阻(zu)、銅(tong)熱(re)電(dian)(dian)(dian)(dian)阻(zu)、PTC陶瓷熱(re)電(dian)(dian)(dian)(dian)阻(zu)、熱(re)敏(min)電(dian)(dian)(dian)(dian)阻(zu)和各種電(dian)(dian)(dian)(dian)阻(zu)型合(he)金(jin)絲等。產品具(ju)有測(ce)量精度高(gao)，性能穩定(ding)、測(ce)試(shi)速度快、抗(kang)干擾能力等特點。

* 產品價格(ge)低，可(ke)靠性好是(shi)Z經濟(ji)實惠的測試設備。

* 采用凱爾文四端(duan)式測量方法，測試(shi)精度高。

* 儀器內附精密基準電(dian)阻，通過校準確(que)保(bao)儀器的(de)準確(que)度和長期穩定性。

* 測試電流比同類型儀器(qi)小，有效地防止自熱現象對測量精度帶來(lai)影響。
