How to Set The Beat of the Pendulum Clock. TIP â Prevention: for wall clocks, always remove your pendulum before taking the clock off the wall. If the pendulum stays in the clock it may scratch the inside of the case as well as change the beat and then the clock may not work.Check The âBeatâ: Listen to the tick-tock on the clock and see if it is nice, even tick-tock. It should sound steady and even like a metronome. Equal time between the TICK and the TOCK.The pendulum needs to swing exactly equal distances from dead center to the left, as from dead center to the right.heck The âBeatâ: Listen to the tick-tock on the clock and see if it is nice, even tick-tock.
