Stasjonære benk-multimetre kan drives med nettspenning. </p><p>En indikator på displayet viser om batteriet er for svakt for å drive multimetret skikkelig. Den aktuelle batterispenningen kan måles med eget multimeter i V-området: Man kopler den positive inngangen (rød kabel) til batteriets to poler, én etter én, og beregner så differansen. Minus, eller fellesinngangen (sort kabel), må aldri tilkoples eget batteri på grunn av fare for skade på instrumentet. </p><p>Avanserte digitale multimetre har gjerne et menypunkt hvor man kan se batterispenningen til enhver tid. </p> <div class="navbox-styles"><style data-mw-deduplicate="TemplateStyles:r23230704">.mw-parser-output .hlist dl,.mw-parser-output .hlist ol,.mw-parser-output .hlist
