For anybody who have an idea...How to test a Zener Diode.
#2
Using an ohmmeter take and put it on the Ohms setting. You should have resistance one way and not the other. Also some meters have a diode setting. A diode is just an electrical valve that lets current flow in one direction.
Here is some info on this. This should help out. This explains it a lot better than I can.

Here is a little on the characteristics of a zener diode.

If you have an adjustable power supply, an ammeter and a current limiting resister of oh, lets say 330 ohms, you could test the reverse current to see what the breakdown voltage is and see if the diode functions properly. You absolutely need a current limiting resistor to protect the diode and the ammeter for when you reach the breakdown voltage.
