ABSTRACT:
The invention provides an improved pulse initiator circuit for attaching to utility meters to generate a pulse signal having a predetermined relationship to the rate of power usage measured by the utility meter. Electronic circuitry is utilized which automatically compensates for differences in individual utility meters permitting the pulse initiator to be used with any standard utility meter without calibration or adjustemnt. The pulse initiator is attached to the utility meter without breaking the meter seal.
