It has a very simple construction.
The indications are independent of the wave-form of supply voltage.
It cannot read closer than half the frequency difference between the adjacent reeds.
Consequently, precise measurement of frequency cannot be made with such a meter.Any change in the physical characteristics of reeds (e . g. length, weight etc.) may change their natural frequency to a considerable extent
