ABSTRACT:
A clock escapement monitoring device and method of accurately adjusting the escapement. The device comprises a sensor for monitoring the mechanical vibrations occurring at each excursion and producing an electrical pulse representative thereof; a standard clock of 100K Hertz; a signal conditioning circuit for conditioning the electrical excursion pulses and providing an audio output for monitoring audio signals representative of the mechanical vibrations; two frequency dividing trains, one for the conditioned excursion pulses and the other for the standard clock signal; and a display counter connected to the outputs of the frequency dividing trains wherein a visual display is produced representing the time of one excursion interval, the average time of ten excursion intervals, and the average time of one hundred excursion intervals; a regulated power supply; and a visual monitor for indicating a low power supply voltage.
