ABSTRACT:
A symmetric monitor calibrator for mounting on a cathode ray tube or monitor with a surface. The calibrator has a case that holds electronic and optic components. Suction cups hold the calibrator to the surface, in which the suction cups are attached to the end of supporting elements that surround the case. At least three supporting elements with a common connecting point to form one support structure are connected to the top of the case. The supporting elements extend out creating a greater diameter than the case. The supporting elements and therefore suction cups uniformly surround the center point of the case to prevent rotation caused by the effects of gravity.
