Imikhiqizo ye -DFUn Multi Multi-Channel Meter ingalinganisa i-voltage, yamanje, namandla emjikelezweni ngasinye ngesikhathi sangempela, iqinisekisa ukusebenza okuzinzile kohlelo lwamandla. Amandla okulinganisa okunemba okuphezulu avumela ukuthwebula okufika ngesikhathi kwezinguquko ezinamandla kunethiwekhi yamandla, ukuhlinzeka ukwesekwa kwedatha okuthembekile kwezinqumo zokusebenza kanye nokulungisa. Lawa mamitha we-DC Energy afaka imisebenzi yokulinganisa amandla esebenza kahle, ukukala ngokunembile ukusetshenziswa kwamandla okuphelele kuwo wonke amasekethe, kusiza ekuphathweni kwamandla nokulawulwa kwezindleko ngokuhlaziywa okuningiliziwe kokusetshenziswa kwamandla.
