ES3000 na'urar gwajin juriya ta dijital (nau'in aiki mai yawa) ita ce na'urar da aka yi amfani da ita don bincika ma'aunin juriya ta ƙasa. Ya yi amfani da babban LCD launin toka mai nuni da fasahar microprocessor don saduwa da buƙatun juriya na gwajin layi biyu da uku. Yana dacewa da sadarwa, wutar lantarki, yanayi, inji dakuna, filin mai, lantarki rarraba layi, hasumiya watsa layi, gas tashar, masana'antu ƙasa cibiyar sadarwa, walƙiya allura da sauransu. Kayan aiki gwajin daidaito, sauri, sauki, kwanciyar hankali da amintacce da sauran halaye.

Microprocessor iko, zai iya ta atomatik gano daban-daban dubawa haɗin yanayin da kuma kasa cibiyar sadarwa tsangwama ƙarfin lantarki, tsangwama mita, da kuma gwajin taimakawa ƙasa pole juriya darajar aiki. A lokaci guda adana 500 saiti na data, juriya ma'auni kewayon: 0.01Ω ~ 2000Ω, ƙasa ƙarfin lantarki kewayon: 0 ~ 100V. Za a iya sa ido da data online ta hanyar sa ido software, USB data upload PC da kuma da musamman fasali kamar lambar kiyaye da kuma m ƙararrawa bayanai.
