DO30-J nau'i uku amfani da matattarar calibrator ne mai hankali junction, DC misali ƙarfin lantarki, halin yanzu misali tushen. (inda AC fitarwa aka nuna a matsayin ainihin ingantaccen darajar). Range daidaitawa za a iya zaɓar hanyoyi biyu na maɓallin ko potentiator. Yana da siffofin nuni na dijital, rarrabuwa mai kyau, kyakkyawan kwanciyar hankali, sauƙin amfani da sauransu. Yana dacewa da dubawa, dubawa, gyara uku da rabi kasa da dijital uku amfani da mita, ƙarfin lantarki mita da kuma halin yanzu mita, da kuma daban-daban kasa da 0.5 matakin mai nuni uku amfani da mita, cross, DC ƙarfin lantarki mita da kuma halin yanzu mita; Hakanan ana iya amfani da shi a matsayin high kwanciyar hankali gwajin wutar lantarki, tare da high-grade misali mita, daidaita 0.2 matakin halin yanzu mita da kuma ƙarfin lantarki mita.
