Voltage may be present in the circuit due to charged capacitors. If so, the capacitors need to be discharged. Set the multimeter to measure ac or dc voltage as required. Turn the dial (rotary switch) to Diode Test mode. It may share a space on the dial with another function. Connect ...
Test for continuity: To test for continuity, touch the two test leads together and check if the multimeter displays zero resistance or beeps. This ensures that the multimeter is functioning properly. Test the LED bulb for continuity: Touch one of the test leads to the base or metal portion ...
Again the test using a multimeter only provides a confidence check that the bipolar transistor has not blown, but it is still very useful.As with the diode, the most likely failures result in the destruction of the transistor, rather than a slight degradation in the performance....
