<p><strong>ES3002雙鉗多功能接地電阻測試儀</strong>（多功能型）又叫雙鉗接地電阻測試儀。其集合多種測量方法于一體的高級接地電阻測試儀，該儀表除了具有傳統(tǒng)打輔助地極測接地電阻的功能外，還具備了無輔助地極測量的*功能。它采用了超大LCD灰白屏背光顯示和微處理機技術(shù)，通過微處理器控制精密4線法、3線法和簡易2線法、選擇法、雙鉗法測量接地電阻測試。采用大口徑電流鉗設(shè)計，利用雙鉗口測量技術(shù)，無需打輔助地極、無需將接地體與設(shè)備隔離，實現(xiàn)了在線測量。廣泛應(yīng)用于電信、電力、氣象、機房、油田、電力配電線路、鐵塔輸電線路、加油站、工廠接地網(wǎng)、避雷針等。儀表具有測試精準(zhǔn)、快速、簡捷、穩(wěn)定可靠等特點。<br /><br /><strong>ES3002雙鉗多功能接地電阻測試儀</strong>由微處理器控制，可精準(zhǔn)檢測接地電阻、土壤電阻率、接地電壓、直流電阻和交流電流。其使用了快速濾波技術(shù)可將干擾減至zui小。同屏顯示輔助電極的電阻值，方便判斷由于環(huán)境因素帶來的測量誤差，便于更準(zhǔn)確測量接地真實阻值。同時存儲500組數(shù)據(jù)，可通過監(jiān)測軟件在線監(jiān)測數(shù)據(jù)，USB數(shù)據(jù)上傳PC并具有數(shù)值保持及智能報警提示等*功能。<br
