UT171工業真有(you)效值萬用表
UT171系列(lie)工(gong)業級檢驗型數字萬(wan)用(yong)(yong)表，可對(dui)(dui)大多數工(gong)業問(wen)題(ti)進行(xing)故(gu)障(zhang)排查。在(zai)(zai)我們日常檢修中，是否因為大型容性(xing)用(yong)(yong)電(dian)(dian)(dian)(dian)(dian)設(she)備(bei)斷電(dian)(dian)(dian)(dian)(dian)后(hou)會存(cun)在(zai)(zai)殘(can)余(yu)(yu)電(dian)(dian)(dian)(dian)(dian)壓，一般萬(wan)用(yong)(yong)表輸(shu)入(ru)(ru)阻抗太高，無(wu)法識別殘(can)余(yu)(yu)電(dian)(dian)(dian)(dian)(dian)壓，因而產生(sheng)誤判而導致設(she)備(bei)時(shi)常發生(sheng)故(gu)障(zhang)或存(cun)在(zai)(zai)安全隱(yin)患。此時(shi)UT171 LoZ低阻抗輸(shu)入(ru)(ru)，3KΩ輸(shu)入(ru)(ru)阻抗可以有(you)效的(de)(de)對(dui)(dui)殘(can)余(yu)(yu)電(dian)(dian)(dian)(dian)(dian)壓進行(xing)放電(dian)(dian)(dian)(dian)(dian)并準確判斷是否有(you)殘(can)余(yu)(yu)電(dian)(dian)(dian)(dian)(dian)壓的(de)(de)存(cun)在(zai)(zai)。同(tong)時(shi)該(gai)系列(lie)儀表具有(you)4-20mA回路(lu)、AC+DC、nS電(dian)(dian)(dian)(dian)(dian)導、可編程(cheng)方波輸(shu)出， VFC變(bian)頻等測量功能(neng)。是一款普遍使用(yong)(yong)于工(gong)業應用(yong)(yong)，電(dian)(dian)(dian)(dian)(dian)機故(gu)障(zhang)排除，電(dian)(dian)(dian)(dian)(dian)氣(qi)工(gong)程(cheng)維(wei)修人員的(de)(de)功能(neng)齊全的(de)(de)檢驗儀表。
