Option 1 : Absolute

Absolute instruments or Primary Instruments:

  • These instruments give the magnitude of the quantity under measurement in terms of physical constants of the instrument, e.g. Tangent Galvanometer, Absolute electrometer, and Raleigh current balance
  • These instruments do not require comparison with any other standard instrument


Secondary instruments:

  • These instruments are so constructed that the quantity being measured can only be determined by the output indicated by the instrument, e.g. ammeter, wattmeter and energy meter
  • These instruments are calibrated by comparison with an absolute instrument or another secondary instrument, which has already been calibrated against an absolute instrument
