Abstract
An adjustable scanning range is provided for vehicle-activated measuring equipment of the type which includes receiver coils positioned on opposite sides of a transmitter such that voltages induced in the received coils from the transmitter are altered as the vehicle passes, the measuring occurring through the application of the induced voltages to a comparison circuit. Altering the input(s) to the comparison circuit by a constant voltage value allows the scanning range to be adjusted.
