Basics of Measurements. Chapter 1. . Measurement. The measurement is the result of the comparison of standard and the unknown quantity. The result of the measured quantity is generally expressed in numeric forms. In other words, the measurement is the process through which the physical parameters like heat, displacement, force etc. is converted into the easily readable numeric value. The cathode ray tube (CRT) is a . vacuum tube.  containing an . electron gun.  (a source of electrons) and a . fluorescent.  screen, with internal or external means to accelerate and deflect the electron beam, used to create images in the form of light emitted from the fluorescent screen. The image may represent electrical .
