Description: <br>This is designed for quick test of signals and voltage in the main board. It can be used to test open circuit or short circuit of BGA and CPU. It uses indicator to indicate every bus and control mode, replacing traditional multimeter, compared with which it is more intuitive. <br> <br> <br> Features: <br>1. 100% Brand new and high quality. <br>2. Designed for quick test of signals and voltage in the main board. <br>3. Used to test open circuit or short circuit of BGA and CPU. <br>4. Replace traditional multimeter with indicator, the result is more intuitive. <br>5. Compatible for all 1151 main board. <br> <br> <br>Specifications: <br>Material: PCB <br>Color: Black <br>Compatibility: for all 1151 main board. <br>Size: 38 * 38 * 3mm / 1.5 * 1.5 * 0.1inch <br>Weight: Approx. 26g <br> <br> <br>Instructions: <br>1. Put 1151 test indicator in 1151 CPU slot and press down the CPU cover plate (note that this time it can't electricity), with 2023 3V battery against the test lamp row needles, all DMI signal lamp will light up. If the light is off, says there are a short circuit. You can shake CPU compression bar, using a multimeter to make a further determination. <br>2. When the above steps are tested normally, install the CPU load in the pass sample step, and use oscilloscope to test whether various voltages, clocks and other signals are normal or not. <br> <br> <br>Package Include: <br>1 x Test Card with Indicator <br>1 x Test Card without Indicator <br> <br> <br>Notes: <br>1. When using the 1151 test card, when the battery is against the drain pin, the indicator is off, it may be that the positive and negative terminals are connected backwards, please replace the positive and negative terminals of the battery. <br>2. After multiple times of use, the indicator will turn on or dim for the voltage of the test lamp is not enough, please replace the battery by yourself. <br>3. Various signals of the tester, such as CPU power supply voltage, may not be detected due to the particularity of 1151 motherboard. Please use the same motherboard for comparison or other methods to judge.1、100% Brand new and high quality. <br>2、Designed for quick test of signals and voltage in the main board. <br>3、Used to test open circuit or short circuit of BGA and CPU. <br>4、Replace traditional multimeter with indicator, the result is more intuitive. <br>5、Compatible for all 1151 main board.
