The markings on the paper are done with one pen or more than one pen of different colours for the creation of a distinguishing effect as and when required. For instance, if the chart recorder measures seismic activity then two different coloured pens might be used for the measurement of velocities and types of waves. Taking into consideration the operation, the chart recorders are available in three basic varieties that are electronic, mechanical and electromechanical.
