Electrical measurement standards
Measurement of electrical current, potential difference, resistance, capacitance and inductance are of vital importance in industrial processes. A number of different types of electrical measuring instruments such as multimeters, bridges, insulation testers, high voltage meters as well as resistors, capacitors and inductors are in use. A number of other equipment, e.g. electronic balances, load cells and analytical instruments, also use electrically operated transducers or sensors.
