2、重量：2kg左右(you)

四、使用說明

將電(dian)池(chi)裝(zhuang)入(ru)(ru)儀表(biao)后，功能(neng)開關(guan)置于“BATT.CHECK”（電(dian)池(chi)檢測(ce)），按(an)(an)下(xia)電(dian)源(yuan)按(an)(an)鈕(niu)，觀察表(biao)針(zhen)(zhen)(zhen)指(zhi)示，指(zhi)針(zhen)(zhen)(zhen)在“BATT.GOOD”線(xian)內，則(ze)表(biao)示電(dian)源(yuan)滿足(zu)儀表(biao)正(zheng)常工(gong)作(zuo)，否(fou)則(ze)須更換電(dian)池(chi)。將E.L端(duan)子接入(ru)(ru)被(bei)測(ce)物，功能(neng)開關(guan)置各電(dian)壓(MΩ)檔(dang)，按(an)(an)下(xia)按(an)(an)鈕(niu)開關(guan)（可(ke)(ke)順時針(zhen)(zhen)(zhen)旋動將按(an)(an)鈕(niu)鎖緊(jin)），即可(ke)(ke)聽到連(lian)續的“嘀....”聲(sheng)。此時，指(zhi)針(zhen)(zhen)(zhen)偏轉指(zhi)示測(ce)量數值，刻度指(zhi)示紅燈(deng)亮讀取橙(cheng)**域內的刻度值，綠(lv)燈(deng)亮讀取綠(lv)色區域內的刻度值。根據(ju)需要，可(ke)(ke)接入(ru)(ru)屏蔽端(duan)（被(bei)測(ce)物屏蔽后，接入(ru)(ru)G端(duan)）。

根據電(dian)壓等級(ji)，儀表分為四種型號：

JDC-1型(xing):500V/1000V/2500V

JDC-2型:250V/500V/1000V

JDC-3型:2500v/5000V

JDC-4型:100V/250V/500V
