Über die graphische Ermittlung der Frequenzabweichung einer Quarzuhr vom Sollwert

Summary

Basing on the well-known relation between the daily rate of a quartz clock running as per mean solar time and the frequency-deviation corresponding to this rate, a simple graphical method is described by means of which it is possible to read the frequency-deviation from the correct value from the smoothed curves of the clock's rate. This is achieved by putting a transparent frequency-scale on the aforementioned smoothed curves.
