3) Check if there is a short circuit or even an open circuit in the capacitor. Step 4: Check the integrated circuits related to the circuit board, as well as the indicators of resistors and other related devices. 3.Online measurement method 1) Power on the circuit board and check if the...
Turn multimeter dial to Ohms or Resistance. Insert black test lead into the COM jack. THEN insert the red lead into the VΩ jack. Connect test leads across the component beign tested. Read measurement on display. Related resources Guide to digital multimeter safety ...
3. Set your digital multimeter on DC mode. 4. Now, suppose you want to check the 4-pin Molex connector that outputs both +12V and +5V. First, connect the Red lead of the multimeter to the Red wire pin of the Molex connector and the Black wire to any ground wire of the Molex conn...
Set the ohmmeter to measure resistance in the 20 K ohm range; "K" stands for kilo, which means thousand. If you have a multimeter, turn its dial to the 20 K ohm scale, and insert its red lead in the common jack and its black lead in the jack marked with the ohm symbol. Test th...
resistance existing between the various circuit locations on the circuit board in order to test it for any short circuits. But, if the visual examination is unable to provide any information regarding the location or origin of the short circuit, obtain a multimeter, then try locating the Board....
From this it can be seen that the circuit in which the current is flowing has to be broken and the multimeter inserted into the circuit.In some circuits where current may often need to be measured, terminals with a shorting link may be added to facilitate the current measurement....
