Desktop Motherboard Repair Analyzer Tester For DDR4 Test Card RAM Memory Slot with LED

Desktop Motherboard Repair Analyzer Tester For DDR4 Test Card RAM Memory Slot with LED

This product is an upgraded version of the first generation DDR4 test light, which supports forward and reverse slot interfaces. It uses the on and off of light-emitting diodes to indicate the open and short circuits of data lines, address lines, and other signals, replacing the traditional method of measuring one by one with a multimeter. It is used to repair motherboards that do not turn on, display, or not read memory, and is a common tool for repairing computers. instructions:

Install 3.3V (CR2032) battery(Battery not included) on the tester and insert them into each corresponding DDR4 memory slot. The motherboard does not need to be powered on. If the test lights are all on and the brightness is consistent, it indicates that the signal line is normal. If any lights are not on or are on excessively, it indicates that the signal has an open or short circuit fault. Use a multimeter to further determine the fault point. (Note: Due to differences in motherboard design and chipset among manufacturers, some signals of the tester may display differently. Please have maintenance personnel compare and determine the fault using the same motherboard.)
