Test the MM325 on a known live source, verify your target circuit is de-energized, and then re-test on the known live source to confirm your meter is functioning correctly. This ensures the 0V reading isn't due to a blown fuse or dead battery.\u003c\/p\u003e","brand":"KLEIN TOOLS","offers":[{"title":"Default Title","offer_id":51657017950519,"sku":"MM325","price":34.97,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2274\/5945\/files\/Klein_Tools_MM325_Digital_Multimeter_Manual_Ranging_600V_AC_DC_Voltage_Tester_with_Backlit_Display_10A_Current_Resistance_Diode_and_Battery_Test_Functions.jpg?v=1770245969"}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2274\/5945\/collections\/Klein_Tools_MM325_Digital_Multimeter_Manual_Ranging_600V_AC_DC_Voltage_Tester_with_Backlit_Display_10A_Current_Resistance_Diode_and_Battery_Test_Functions.jpg?v=1779393723","url":"https:\/\/www.1toptools.com\/collections\/multimeter.oembed","provider":"1 Top Tools","version":"1.0","type":"link"}
