Classification of Instruments
Classification of instruments can be carried out in two categories: Absolute Instrument These instruments give the magnitude of the quantity under measurements in terms of physical constants of the instrument. The quantity to be measured will be given in terms of deflection and the constant of the instrument. The examples of this class of instruments […]
