Imikhiqizo ye -DFUN Multi-channel Meter ingakala i-voltage, yamanje, namandla esekethe ngayinye ngesikhathi sangempela, iqinisekise ukusebenza okuzinzile kwesistimu yamandla. Amandla okulinganisa okunemba okuphezulu avumela ukuthwebula okufika ngesikhathi kwezinguquko eziguqukayo kunethiwekhi yamandla, ukuhlinzeka ngosekelo lwedatha oluthembekile ezinqumweni zokusebenza nezokulungisa. Lawa ma-DC Energy Meters afaka imisebenzi ephumelelayo yokukala amandla, ukulinganisa ngokunembile ingqikithi yamandla asetshenziswa kuwo wonke amasekhethi, esiza ekulawuleni amandla nokulawulwa kwezindleko ngokuhlaziywa okuningiliziwe kokusetshenziswa kwamandla.
