Opis produktu: PC AGP PCI-E X16Dual-Purpose Socket Tester Display image Video Card Checker Tester image Card Diagnostic Tool

colour: black Material: PCB Package Contents: 1 * PCI-E diagnostic card Only the above package content, other products are not included. Note: Light and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm. 1. AGP, PCI-E tester is mainly used to test the open circuit and short circuit of the data bus connecting the computer image card chip CPU and the computer motherboard PCI to the ground2. When repairing the computer's image card failures such as non-display, blurry or unstable display, it is not necessary to use a multimeter to measure the PCI bus interface between the image card golden finger and the motherboard one by one. This image card tester can quickly detect the open circuit and the CPU Short-circuit failure, with100% accuracy, is a standing tool for repairing image cards. 3. When repairing the computer image card, if the display card does not display, the screen is blurred, etc., first check the appearance for obvious burnt marks, whether the PCB is obviously disconnected, and whether the voltage of each group is normal. If it is normal, use a tester to further measure the CPU Whether the data cable connected to the motherboard PCI interface is normal. 4. Add a12V power supply to the tester, insert the fault card into the corresponding slot, press the Press switch in the upper right corner, the corresponding indicator on the tester should be all on, if it is not on or flashing, the brightness will change significantly , Or caused by the open circuit or short circuit of the main chip CPU, use the universal meter to further determine the fault point
