Definition : Measuring instruments designed to measure the flow of electric current (either direct or alternating, DC or AC respectively, or both) along a conductor of an electric or electronic circuit, usually expressed in amperes. These instruments typically consist of electromechanical (analog) or more frequently electronic (usually digital) instruments with appropriate leads. Practical instruments can perform the most common current measurements needed for electric and electronic equipment, circuits, and components. Ammeters are mainly used in healthcare facilities in inspection, preventive maintenance, repair, and calibration of medical devices and other hospital equipment.
