| Abstract |
The paper presents a method, applied for calibration of premagnetized linearity correctors, that are used in CRT monitors and TV sets. The magnetization procedure of the corrector's permanent magnet to the saturation level, followed by its partial demagnetization using a pulse-generating device is described. Comprehensive test site, controlled by LabView software is presented, with special emphasis on demagnetization voltage determination. When a proper algorithm is implemented, the corrector's operating point can be set to the required tolerance range (below 3 %) and within short period of time (less than 4 s), which is important for cost-effective mass-production. |
