Features
The computer monitor test signal generator according to data from abroad to improve production of 15 kinds of high-precision resolution test signal generated by the microcontroller, can be widely used for display manufacturers test, color monitor maintenance units, color display sales unit testing occasions (support to test different resolution Caixian).
Product advantages: small size, easy operation, high precision and high cost.
The color display is used to repair units, such as the use of the host computer as a signal source, easy to damage the graphics card, and inconvenient maintenance operation.
For Caixian sales company, rapid detection color display is normal.
For color display manufacturers, 15 kinds of high precision, and resolution of the signal source to meet the testing requirements of the display.
[Use]
9V power supply is connected (in the positive external negative voltage of 7V-12V can be), just the tester can be connected to the monitor's 15-pin plug.
