If any one could identify please e-mail me .....thanks inadvance Quote Link to comment Share on other sites More sharing options...
Kevin Weddle Posted August 22, 2004 Report Share Posted August 22, 2004 Use a 12volt source and a 10kohm resistor. The voltage of the zener will be apparent. Are you sure it's bad? A diode will often display the resistance that surrounds it, thus measuring a low voltage. Zeners will display a voltage under low currents so you don't have to worry about testing it.
