接地(di)電阻測試儀性(xing)能特(te)點：

1、測(ce)量(liang)的工(gong)頻等效性好。測(ce)試電流波(bo)形(xing)為(wei)正弦波(bo)，使用兩(liang)種頻率(lv)進(jin)行測(ce)量(liang)。

2、抗地(di)電壓干(gan)擾能(neng)力(li)強。接地(di)電阻(zu)(zu)測(ce)試(shi)儀(yi)采用異頻法測(ce)量，配合現代軟硬件濾波(bo)技(ji)術，使得(de)接地(di)電阻(zu)(zu)測(ce)試(shi)儀(yi)具有很(hen)高的抗干(gan)擾性能(neng)，測(ce)試(shi)數據(ju)穩定可靠。15V工(gong)頻（50Hz）干(gan)擾電壓帶來(lai)的誤(wu)差僅為0.001Ω。

3、精度高。接地(di)電阻(zu)測試儀可(ke)用來測量接地(di)阻(zu)抗很(hen)小的(de)大型地(di)網。

4、功能強大。接(jie)地電阻測試儀可(ke)測量相關標準(zhun)規定的接(jie)地裝置的全部(bu)特性參數。不僅可(ke)測量接(jie)地阻抗，還可(ke)測量出電阻分量和電抗分量。

5、接(jie)地(di)電阻測(ce)試儀(yi)具備斷線報警(jing)功能，避免(mian)了(le)錯(cuo)誤測(ce)量。

6、操作(zuo)簡單(dan)。全中(zhong)文菜單(dan)式操作(zuo)，直接顯示出測量(liang)結果(guo)，且自帶微(wei)型打印機可(ke)現場打印測量(liang)結果(guo)。

7、布(bu)線勞動量小，無需大電流線。

8、接地電阻測試儀體積(ji)小、重量輕，方(fang)便(bian)攜帶。

接地電阻測試儀(yi)測量事項及維護保養

1、測量保護(hu)接(jie)地電阻(zu)(zu)時，一定要斷開電氣設(she)備與(yu)電源連接(jie)點。在(zai)(zai)測量小(xiao)于1Ω的接(jie)地電阻(zu)(zu)時，接(jie)地電阻(zu)(zu)測試儀應分(fen)別用導線連在(zai)(zai)接(jie)地體上，C2在(zai)(zai)外側P2在(zai)(zai)內側

2、測量接地電阻時反(fan)復在不同(tong)的方向測量3-4次，取其平均值。

3、測(ce)量大型接(jie)地(di)網接(jie)地(di)電阻時，不能按一般(ban)接(jie)線方式測(ce)量，接(jie)地(di)電阻測(ce)試儀可參照(zhao)電流表、電壓表測(ce)量法中的規定選定埋(mai)插點。

4、若測試回路不通(tong)或超(chao)量程時(shi)，表頭顯示(shi)“1”，說明溢出，應檢查測試回路是(shi)否(fou)連接好或是(shi)否(fou)超(chao)量程。

5、接地(di)電(dian)(dian)(dian)(dian)阻測(ce)試儀當電(dian)(dian)(dian)(dian)池(chi)電(dian)(dian)(dian)(dian)壓低于(yu)7.2V時，表頭顯示欠壓符號(hao)“←”，表示電(dian)(dian)(dian)(dian)池(chi)電(dian)(dian)(dian)(dian)壓不(bu)足(zu)，此時應插上電(dian)(dian)(dian)(dian)源線(xian)由交流供(gong)電(dian)(dian)(dian)(dian)或打開(kai)儀器(qi)后蓋板更(geng)換干電(dian)(dian)(dian)(dian)池(chi)。

6、如果使(shi)用(yong)可(ke)充電(dian)池(chi)時，可(ke)直(zhi)接(jie)插上電(dian)源(yuan)線利用(yong)本(ben)機充電(dian)，充電(dian)時間一般(ban)不(bu)低(di)于8小時。

7、存放保管(guan)本表石時，接地電阻測試儀應(ying)注意環境溫度和濕度，應(ying)放在干(gan)燥(zao)通(tong)風的地方為(wei)宜，避(bi)免受(shou)潮，應(ying)防止酸堿及(ji)腐蝕(shi)氣體(ti)，不得雨淋，暴曬，跌落。
