Noun
slave clock (plural slave clocks)
A clock that is synchronised by a master clock.
Slave clock synchronization is usually achieved by phase -locking the slave clock signal to a signal received from the master clock. Source: Internet
To adjust for the transit time of the signal from the master clock to the slave clock, the phase of the slave clock may be adjusted with respect to the signal from the master clock so that both clocks are in phase. Source: Internet
The slave clock is set to run slightly slow, and the reset circuit for the gravity arm activates a pivoted arm that just engages with the tip of the blade spring. Source: Internet
If the slave clock has lost too much time, its blade spring pushes against the arm and this accelerates the pendulum. Source: Internet
Once the gravity arm is released, it trips a mechanism to reset itself ready for release by the slave clock. Source: Internet
