Linear radio mechanic device `` Videotest-2M ''.

Instruments for adjusting and controlling the PTA.The device of linear radio mechanics "Videotest-2M" has been produced by the Leningrad Research Institute of Television since 1988. A modern television receiver for a color image is a very complex radio-technical device, designed for long-term operation. To ensure its stable operation for a long time in a number of TV circuits, automatic parameter maintenance systems are used, however, due to the aging of electrical radio elements, some quality parameters may go beyond the permissible limits. In these cases, it becomes necessary to adjust, and possibly repair. Setting up and repairing color TVs at home is a very complex and time-consuming process. It is possible to significantly speed up the troubleshooting and improve the quality of the repair and setup of the TV using the linear radio mechanic device Videotest-2M. It is a small-sized portable television sensor providing the formation of test signals, measurement of direct and alternating voltages, resistance values ​​with digital indication.
