AGP slot tester is used to test open circuit or short circuit of PC motherboard north bridge chipset. When the motherboard does not display, while the CPU would not work or when the CPU work well and the AGP display card does not display, AGP slot tester can be used to test the error.
Note: when testing motherboard display, most repairers only test the CPU socket and PCI data cable, address cable. However, such testing only covers few cables of BGA. Therefore, it is difficult to repair it successfully. It is recommended to use multimeter or AGP slot tester to test every slot of motherboard such as DIMM, AGP, PCI-E, and IDE etc. When the open circuit or short circuit point can be tested, error can be confirmed.
AGP带灯测试仪AGP带灯测试卡AGP带灯阻值卡使用说明： 1、AGP带灯测试卡用来测试电脑主板北桥芯片的开路、短路故障。 2、如主板出现不显示，CPU不工作，或主板CPU运行正常，AGP显卡不显示，喇叭叫连续的三声，这时需要用AGP带灯测试卡来判断故障。注意：在维修不显示的主板时，大部分维修人员只是测量CPU座和PCI的数据线，地址线，殊不知只是测试了BGA很少的一点线路，常常使维修陷入困境，修复率极低，现推荐维修人员借用万用表或测试卡测试主板的每个转接槽，如DIMM，AGP，PCI-E，IDE等各种接口，只要测出开路短路点，即可确定故障点。
