1)As the instrument coils are air cared, so these instruments are free from hysteresis and eddy current errors. 2)These instruments can be used on both a.c. and d.c. and since they have a precision grade accuracy, they are very useful as transfer instruments. 3)Electrodynamometer voltmeters are very useful where accurate rms values of voltage, irrespective, of waveforms, are required. This is also true for an ammeter where the two circuits have the same time constant. 4)They have a precision grade accuracy for frequencies up to 40 to 500 Hz. The low range being decided by the oscillations of the pointer. Lower grade instruments can be used for frequencies up to 10KHz. read less
