Supports for intel / AMD motherboards with DDR2 and DDR3 interfaces without external power supply.2. Use LED to indicate the open and short circuit of the data line address line, used to repair the motherboard that is not turned on.3. Due to different motherboard design, some lights may not be lit. Can use the same motherboard to judge the fault.4. When testing the motherboard of DR3, as long as the lamp is fully lit, it means normal, no need to test the resistance of the address line.5. Finished by heat treatment, it is high hardness and durable.Instructions for use:1. Install the 3V (CR2032) battery on the tester, test each memory slot of the corresponding DDR2, DDR3 motherboard. The motherboard does not have power, press the button switch on the tester, the test lamp is all bright and the brightness is the same. The signal line is normal, if the light does not shine or special bright, this signal has open circuit short circuit fault. (Note: In the test for intel motherboard, motherboards do not connect the CPU and a variety of connection cards can be measured in the test for AMD motherboards (such as 940 motherboard, AM2 motherboard, 1207 motherboard, 1366 motherboard), to plug in CPU, test light Will be bright.2. In the test DDR2 motherboard, the address line no pull-up exclusion, all the lights all bright, that normal, if the pull-up exclusion, the address line lights, only that exclusion no open, but also with the pointer Table to further determine whether the BGA address line open. (How to determine whether the pull-up exclusion, the pull-up exclusion generally are designed in the memory slot next to the general There are several exclusion, one end connected to the address line, one end of the power supply)3. Pointer table to determine the address line method: the pointer table is pulled to X1 that is one ohm of the stalls, black table pen then motherboard, measured with a red table pen, respectively, DDR2 address line measurement hole, address line resistance that BGA address Line without welding, such as a larger swing, indicating that there are BGA solderable PCB or broken wire failure.I have some ideas of what it is trying to say (and some complete confusion too) but I won't post what I think so as not to bias someone else's opinion

content: I think this board just sends current into the pins and the internal diodes in the chips complete the path. If a pin isn't connected then the LED won't light but I'd say this tester is very crude to say the least. I don't think this is a very useful tool to have because you likely won't be able to fix a motherboard reliably anyway.

content: Actually I asked if someone could make sense from the user manual, not whether they think it is of any use as a daignostic toolThe things are so cheap then I don't see a problem in trying one to find out if it is any use, to be honest.If it can find open circuit or short circuit address and data lines between the DIMMs and CPU or DIMMs and North Bridge I would think that is a rather useful diagnostic tool - unless there is a better way to find these sort of faults.Here is what I can make out from the instructions....Instructions for use:1. Install the 3V (CR2032) battery on the tester, test each memory slot of the corresponding DDR2, DDR3 motherboard. The motherboard does not have power, press the button switch on the tester, the test lamp is all bright and the brightness is the same. The signal line is normal, if the light does not shine or special bright, this signal has open circuit short circuit fault.seems fairly straight forward - you test the motherboard un-powered(Note: In the test for intel motherboard, motherboards do not connect the CPU and a variety of connection cards can be measured -Intel boards don't need the cpu fitted, presumably because they have a Northbridge between CPU and RAMin the test for AMD motherboards (such as 940 motherboard, AM2 motherboard, 1207 motherboard, 1366 motherboard), to plug in CPU, test light Will be bright. -AMD boards do need the CPU fitted2. In the test DDR2 motherboard, the address line no pull-up exclusion, all the lights all bright, that normal, if the pull-up exclusion, the address line lights, only that exclusion no open, but also with the pointer Table to further determine whether the BGA address line open. (How to determine whether the pull-up exclusion, the pull-up exclusion generally are designed in the memory slot next to the general There are several exclusion, one end connected to the address line, one end of the power supply)I think this is trying to say that on DDR2 boards if the address lines have no pull up resistors and the LEDs light then there is not an open circuit fault. If it does have pull up resistors and the LED lights it only proves the pull up resistor is not open circuit. The stuff about the 'pointer Table' I have no idea what that is supposed to mean?? The pull up resistors if present are next to the DIMM slots?Feature 4. When testing the motherboard of DR3, as long as the lamp is fully lit, it means normal, no need to test the resistance of the address line.DDR3 boards don't have pull up resistors, I assume.3. Pointer table to determine the address line method: the pointer table is pulled to X1 that is one ohm of the stalls, black table pen then motherboard, measured with a red table pen, respectively, DDR2 address line measurement hole, address line resistance that BGA address Line without welding, such as a larger swing, indicating that there are BGA solderable PCB or broken wire failure.This is trying to tell me to test the address lines with the multimeter on resistance range (I assume this is necessary as a further test if i have a DDR2 board with pull up resistors). It seems to refer to an analog meter (larger swing) I have no idea what that 'Pointer Table to determine the address line method' and what is this 'X1 that is one ohm of the stalls'? red table pen and Black table pen = multimeter probes?Is that all about right, and what do the bit's I can't decipher mean?
