# How do You Test a Diode?

To test a diode you need to use an analog or a digital multimeter. To do this, remove the diode lead and make sure there are no back circuits. Set your meter to x1 ohms range and touch the black probe to the cathode and the red one to the anode.

 1. Obtain the data sheet for the specific diode or thyristor you are using. Look for the I-V curve on the data sheet. Look for a graph that has "voltage" or "V" http://www.ehow.com/how_7941735_test-thyristor-dio...
 The diode must be isolated from any parallel current paths to test. check resistance both directions through diode. readings should show an open (or very high resistance) one direction http://wiki.answers.com/Q/How_is_it_possible_to_te...
 To test a diode, first remove it, then use a test meter with a diode check facility. Test component first one way around, then the other. It should give a 1 in one position, and 0 http://www.fixya.com/support/t1480022-test_diode
 Multimeter- Diodes allow current or voltage to flow one way and not the other. Use the probes and see which way current flows. If current ( voltage flows both ways you have a deffective http://answers.yahoo.com/question/index?qid=200905...
