Electrical measuring instruments symbols. Symbols of counters and electrical integrators. The electronic instrumentation are devices for measuring and testing of physical quantities or performance of electrical equipment circuits or components. Below is the list of measuring instruments used in electrical and electronic work. Use it to design the electromechanical device schematics and electronic circuit diagrams.

The wattmeter is an instrument for measuring the electric power in watts of any given circuit. These electrical units of measurement are based on the international metric system also known as the si system with other commonly used electrical units being derived from si base units. The standard units of electrical measurement used for the expression of voltage current and resistance are the volt v ampere a and ohm ω respectively. Note there are 12 supplements.

The asterisk is replaced by the letter or symbol for the quantity count. Instrument for example a voltmeter is an instrument used for measuring the electrical potential difference between two points in an electric circuit. Name purpose ammeter ampermeter measures current capacitance meter. The symbology of the instrument it is placed in a circle of 7 16 or 12 mm see below was in the top there is the.
