Watch timing machine

A time scale ( also Chronokomparator of French: chronocomparateur ) is an electronic device to detect an irregularity in the path of a clockwork. The strokes of the movement can be accommodated with a structure-borne sound microphone, or detected on the basis of the vibration, and compared with a known frequency. Usually referenced with a quartz time base and the result recorded. Thus, the method provides a simple and fast way to response errors and position errors observed.

It can also be a faulty waste ( limping gait ) and with electronic time scales the amplitude of the balance are analyzed.

Equipment older type writing for each stroke of the clock a short line on a continuous strip of paper. The slope of the lines formed then displays the response errors of the clock, the distance between the lines is an indication of the beat error. Modern devices have an electronic display that digitally displays all relevant data. Nevertheless, such a term is required, a printer must be connected.
