1、The LCD displays various parameters such as output voltage and PG.When each parameter exceeds the normal value, the buzzer will sound a warning sound, and the corresponding value will flash 2、This power tester only needs to be connected to the ATX connector of the power supply to easily and intuitively know whether the output of each power supply is normal. 3、Can detect ATX, BTX, ITX, TFX computer power, and can display the voltage and PG value of each group of LCD, quickly detect the performance of computer power. 4、It can measure the voltage of each group of the power supply 3V / + 5V / + 12V / -12V / SB + 5V / PG. If there is a fault, the buzzer will automatically alarm and the output wire P4 / P6 / P8 / SATA / IDE 5、External DIE / SATA / P6 / P8 is light display, no LCD display voltage 6、Only 24pin or 20pin can be connected to the LCD display voltage. Item Type: Power Supply TesterMaterial: Aluminum alloySupport 20Pin, 24Pin ATX power supplySupports SATA powerSupport 4Pin, 8Pin interface of P4Support PCI-E graphics card 6Pin power connectorSupport Xeco power interfaceSupport floppy drive power interfaceSupport standard 4Pin power interface SATA interfaceTest voltages are + 3.3V, -12V, + 5VSB, + 12V1, + 12V2, + 5VFeatures: PG automatic alarm, LCD shows the situation of each voltageOperation Method: A. Insert the power supply 20PIN or 24PIN and P4, P6 or P8 plug into the corresponding position of the power tester. (If you plug in the 20PIN or 24PIN interface tester to alarm and display LL, you need to plug in 4P! Please be sure that 4P must be inserted in the 4P position!)B. Turn on the power, and there will be two beep sounds at the same time. If the values in each group are not blinking, it means that the power input power is normal.C. If the voltage signal of a circuit is not detected (such as 20PIN or 24PIN connector) or the detected voltage is outside the normal range, the buzzer will issue a "dipping" warning sound for a long time, and the corresponding voltage or PG value is displayed If the state is flashing, it means that the power supply is faulty!Specifications: Voltage Input: 20 / 24PIN (ATX power)Voltage Detection: + 12V -12V + 5V -5V + 3.3V 5VSB 12VPGConnection Port: Floppy HDD COROM SATA 4pin (P4) 8pin (Dual-CPU) 6pin (PCI-E)
