Abstract:

In order to reduce the time of the observations and, consequently, to increase their accuracy, a synchronous clock with stroboscopic registration was used. This clock was driven by alternating current, the frequency of which was set by the primary frequency standard of the All-Union Scientific-Research Institute of Metrology VNIIM. The pendulum-period values were obtained in a few minutes of observation with a precision that is unattainable in eight hours of observation with a chronometer.
