Mechanical Resonance Type Frequency Meter

A mechanical resonance type frequency meter indicate the supply frequency of the circuit directly and is very much convenient for most practical purposes.   It is a very simple instrument and has got an advantage of giving reading free from errors due to change in temperature, waveform and magnitude of applied voltage. Construction of Mechanical …
