The seismograph works as follows. A pen, along with a particular calculated amount of (small) weight is attached to a spring. The other end of the spring is attached to a heavy and stable(so that it can with stand the earthquakes) base support. When an earth quake occurs, the movement of the smaller weight is recorded on a roll of moving paper by the pen. Then the extent of the earthquake is measured by those graphs(seismographs).
John Miline invented the first modern seismograph in 1880
A seismometer (or the older device called a seismograph) records the seismic waves from earth tremors.+++There is a difference there: a seismometer would simply register instant vibration; a seismograph records the vibrations with time so shows the whole picture.

explain why a seismograph would not work if the pen vibrated along with the rest of the machine.

I relly don't Know but the thing that I know thet seismograph and richer scale is the same meaning so please check it and write it THANKS
Here are some sentences.Scientists use a seismograph to measure movement in the earth.The seismograph showed that an earthquake had occurred.
because if the pen vibrated then the seismograph wouldn't work and it would defeat the purpose. the machine only works if the pen is still. if the pen is still the machine will guide it by the heartbeat lines the pen creates.

what is the market value for seismograph
earthquakes are measured by seismic waves so scientists use a seismograph. there are a bunch of seismographs at a station and each one records the same stuff according to the p, s, and surface waves.
the purpose of the seismograph is that it tells you when a earthquake is coming. :)
A seismograph was created to measure out the magnitude of earthquakes.
Humorous answer: A seismograph never answers; it just waves.
seismograph is called 'bhukamplekhi' in hindi
