Testing Power Cord Continuity

手順1 Set the multimeter to continuity test mode



• Unplug the power cord from the device and from the AC outlet. Failure to do so can result in electrical shock or death.
• Set the multimeter to continuity test mode.
• The setting is symbolized by a diode or sound wave symbol as seen in the pictures. If the meter is set to the correct mode, you should hear the meter beep when the leads are touched together.
• Verify that the positive lead is plugged to the voltmeter/ ohmmeter outlet.

手順2 Test for a break in the cable

• Test for a potential open circuit by using one multimeter lead to touch one of the prongs on the AC side of power cord. Use the other lead to touch one end of the console side of the power cord.
• If there is an adequate electrical connection, the multimeter will continuously beep. A short beep does not mean that there is continuity. If it does not beep the first time, try using the lead to touch the other prong.
• Repeat the above directions in step 2 for the other outlet and prong of the power cord.
• If the multimeter fails to beep on any of the occasions outlined above, your power cord is open. In other words, you will need to replace the power cable.

Est-il possible de brancher sur une autre prise alimentée pour savoir si cordon et appareil sont non défectueux ??? Sans danger; faire sauter fusibles etc. Merci.

手順3 Test for a short
• Once you have verified that the power cord provides an adequate electrical connection, you will have to test that the cable is not shorted.
• Test for a potential short circuit by touching each prong on the AC side of the power cord.
• If the multimeter beeps, your power cord is bad and must be replaced immediately.
• If your power cord is shorted, do not attempt to replug the cord into the AC outlet.
• If your power cord has passed all of the steps above, then you have successfully tested that your power cord is in working order.
