The principle of compatibility holds that the motion of the dis play should be compatible with (or m the same direcbon as) the motion of the machine and its control mechanism For example, a display increasing m numer ical value should indicate that the mechanism being measured is also increasing Furthermore, a pointer that moves to the nght to show an increase should have its cor responding control mechanism designed so that 226 a rightward movement of the control will in crease the machme value and the correspond ing display output value Principle of arrangement. As the design of the display is important, so too is its location or arrangement with other displays A poor arrangement of displays can be the source of error Sometimes dials must be arranged in groups on a large control panel If all the dials must
