    特 點(diǎn)
  
      
  
      
    
      1. 890PR是非接觸式量測(cè)的檢相計(jì)，它藉由LED的顯示和蜂鳴器的聲音，來(lái)查驗(yàn)三相交流
      
      電壓系統(tǒng)的狀況。
      
      2.   具有檢測(cè)相位和相序的雙重功能。
      
      3. 自動(dòng)關(guān)機(jī)功能(約五分鐘)。
      
      4.   鱷魚(yú)夾上有顏色貼紙區(qū)分，由於採(cǎi)用不接觸裸銅檢測(cè)，只要將鱷魚(yú)夾夾住電源線(xiàn)外部
      
      即可檢測(cè)，因此安全度高。
      
      5.   具有C亮設(shè)計(jì)，可在強(qiáng)光下或昏暗處辨識(shí)檢測(cè)狀況。
      
      6. 儀表背面附有四顆強(qiáng)力磁鐵，可懸掛於配電箱外殼，方便操作人員使用。
      
      7.   應(yīng)用電壓及頻率寬廣，分別為75V~1000V交流  電壓45~65Hz。
