The PM 5639/25 Miniature color Analyzer is used for automatic manufacturing of CRT based display monitors and for quality control. The size of the sensor allows measurement at different positions on the monitor, even very close to the corners, in order to evaluate display uniformity. The adjustment may include black level, the color of “black”, contrast level, the color of “white” and the color balance and luminance level at any point in between. The communication between the sensor and the controller is based on an RS-232 standard interface. The PM 5639/26 includes a PM 5639/93 Miniature Color Sensor, a power supply, cables and a software package. The PM 5639/93 Miniature color Sensor can be used in multi-sensor automatic manufacturing systems. Monitors used in TV sets have traditionally been aligned based on measurements taken in the centre only. In modern microprocessor controlled monitors used for graphics it is now possible to make individual alignment at different positions on the display.
