HOW TO TEST ZENER DIODE
by digital multimeter and Analog multimeter
ZENER DIODE TESTING Zener diode is a subtype of a diode and it use on circuit as a different function from standard diode. Standard diode we use it as forward bias mode but for Zener diode we use it as reverse bias mode on circuit. When applying forward bias to zener diode it will conduct and let current flow as standard diode , another condition when applying reverse bias to zener diode it will not let current flow until the voltage supply is over the zener breakdown voltage then it will let current flow.
Basic Circuit of zener Diode
How to check zener diode , it has more detail then checking standard diode as it is a subtype of diode so in some condition checking method is as same as standard diode. Before checking you have to know important technical detail of multimeter. We set analog multimeter to range Rx1 or Rx10 , let consider at the test lead there is 3VDC 150mA for Rx1 range and 3VDC 15mA for Rx10.
