Do not skip this step. Safety should be your primary concern during a power
supply test with a PSU tester.
•
Remove anything conductive from your hands (e.g. metal rings, watches, or
bracelets) before testing a PSU or working inside your computer.
•
Only use the original cables that comes with the tester. The PCIe cable that
comes with the tester, is not a standard cable and is custom-made for the
tester. Using other cables could lead to short circuit between the voltage rails.
•
Make sure all the cables are fully inserted
. A loose connection introduces
more electrical resistance which can lead to melting of the wires under high
load (or even a fire).
•
In the case of a dramatic failure of the device under test, you may see smoke
coming from the power supply or inside the case or smell a burning. In this
case unplug the power supply from the
wall
. Do not touch the PSU or the PSU
Tester in such circumstances.
•
Always have someone monitor the testing in case the device under test
suddenly fails. Do not start a test and walk away.
•
If the PSU Tester is inline (connected to both power supply and motherboard),
do not power up using the keypad on the tester. Instead, use the PC power
button. This is just a precaution against poor engineered power supplies that
do not meet ATX standards and can prevent a short on the PS_ON line.
•
In standalone mode the tester will dissipate 4Watts of power (in order to place
a test load on the PSU). This can result in the base of the tester becoming
warm to touch after a short period of time. The tester will automatically
terminate testing after 1 minute to avoid overheating.
