he SD power supply tester is a robust voltage, tester for PC-power supply, ATX . BTX and ITX compliant, power supplies can be tested.
LCD`s indicate the status of voltage .The PC / SPS is suitable for the ambitious hobby user , as well as for a quick functional check in specialized trade.
The methods of operation:
Plug power supply 24 PIN and P4 , P6 or P8 into the corresponding jack of the power test suite
Power on the supply of power, will hear \"DuDu\" ring , if no flicker then the power supply output voltage is normal.
If a certain voltage signal was not detected, or the detected voltage value over the normal, will issue a \"DuDu\" long buzzer ; if the corresponding voltage value or PG flicker too, then the power is failed.
