Abstract :
INDICATING or recording frequency meters in the 1-per-cent commercial frequency class use various circuits to obtain their indication. In all these circuits the instrument mechanism forms part of the circuit. The cross-coil type, the moving-iron type and the vibrating-reed type all have mechanisms that are built specifically for these meters, and these mechanisms have very little other commercial uses.
