The above is a standard multimeter you can find easily
in the market. |
The above is a simple guideline on what are the functions of a multimeter. |

| A closeup on the multimeter where you connect the test probes. |
We are only covering some areas so stick with the settings shown above on how you connect the probes. The red probe is connected to the V-Ohm-mA hole and the black probe is always connected to COM
|
|
|
|
| To see if your multimeter is working properly, set it to the speaker icon as shown above. Cross the two probes and if you hear a beeping sound, that means it’s working properly.
|
Now to test resistors, set it to 2000 at the Resistor Test Area. |
|
|
|
The resistor that I am testing is a 1/4 watt 920 Ohm
resistor. When you connect the probes on each end of the
resistor, the multimeter will give you the resistance reading.
|
To test voltage from PSU, set it to 20 DCV of the Voltage Test Area. |
|
|
|
Please take extra care not to short the probes while connecting to the PSU molex. Make sure that the Red
probe is connected to the yellow wire slot of your molex and the black probe to the black wire slot. If you are unsure, we urge you not to test voltage of a PSU as it can short and blow your multimeter or PSU.
|
The above is telling you that the voltage supplied by the 12V rail from your PSU molex is 11.95volts. |

|
This is one of the best features in a multimeter. You can
test your LEDs to tell their colors and their condition. Set it to the speaker icon. |
Simply poke the two poles on your LED as shown above.
