The School Clocks
When you are young your world revolves around the school clocks. Oddly enough they were not created just to be the ban of millions of children, they do serve a purpose. The school clock tells your teacher when school should start and when it should end. Of course that is what a clock should do but they s are specially made so that each classroom always has the exact same time. Can you imagine if each was just a little bit off?
Everybody knows that some runs faster or slower then other. Sometimes it is because they were set incorrectly and sometimes it is for other reasons. School clocks are always the same. Why? Does the world of school clocks just conspire to all run the same to keep kids in their seats for some nefarious reason or is there a trick to it? Actually there is a trick to it. You see they are what is known as a master clock system.
A master clock system is a system that has one clock as the master that is connected to one or more "slave" clocks so it can control them. This type of school system has been in place since the early 1900s. It seems to be a case of if it isn't broke don't fix it.
The way they work is the master clock sends out an electronic pulse to each of the slaves. When the slaves receive the signal the hands on the move forward the correct amount.
There are a few steps to take before setting a school clock system. First check the main one to see if it is digital or analog. Analog clocks have hands and a traditional clock face, while digital ones show the numbers on a LCD display.
The next step to setting school clocks is to set them. For an analog one it is as simple as moving the hands into the position needed to reflect the correct time. For digital you will need to press a button or two.
Once the main or master clock is set the slave or secondary clocks will change to reflect the new setting. If the secondary one do not change or do not run correctly, you can repair them by checking the wires. Because the master clock sends out a signal to advance the secondary clocks if a wire is broken it will not function correctly.
