Zener Diode Tester

By on June 11, 2013

My repair friend Andre from Trinidad and Tobago had successfully built a zener diode tester. The diagram was taken from the bonus report found in the Power Supply Repair ebook website at http://www.PowerSupplyRepairGuide.com  Besides testing zener diode, this tester can be used to test on voltage regulator IC, LED, Diode, Small non polarity capacitor, battery voltage and continuity. This tester was nicely built and you can see the photos below.

    why not share the schematic diagram of this zener diode tester so we can try to build our own and prove that it really works out
