1. Plug-in 24pin and plug-in (P4 / P6 or P8) connector into the tester before turn on power.
- 20pin ATX PSU: use P4 connector.
- 24pin ATX PSU: use P6 connector.
- EPS PSU: use P8 connector.
2. Turn on your power supply
3. LCD show each voltage and P.G value on the screen automatic and you can hear 2 beep sounds.
4. ATX power output connector checking one by one.
- If power output is working, the LED will light on
- If power output failed, the LED will not light on.
5. Plug-in (HDD/Floppy) connector and check LED light. (+12V1/+5V).
6. Plug-in SATA connector and check LED light (+12V1/+5V/+3.3V).
7. Remove the connector after your checking.
8. DO NOT plug-in 2 connectors in to the tester at the same time. ( Only 24pin and (P4/P6/P8)
9. Abnormal voltage detected will not display on the screen.
10. No voltage detect, "LL" will display on the screen.
11. Detected Voltage lower than Min. value, "LL" will display on the screen.
12. Detected voltage higher than Max. value, "HH" will display on the screen.
13. When detected voltage is lower than table value (A), will alarm.
14. When detected voltage is higher than table value (B), will alarm.
15. P.G value detected lower 100ms or higher 900ms, P>G value is abnormal and alarm.
When abnormal happened, it will alarm and relative digit blink on the screen.
Each voltage normal range:
Reference field Low (A) and High (B)
+/-5%: +5V, +5VSB, +3.3V
+/-10%: +12V1, +12V2, -12V
