Zener Diodes

The DCA Pro supports Zener diodes (and Avalanche
diodes). Additionally, the instrument can measure the Zener
voltage*.
Connect any pair of the 3 test leads to the Zener diode. Following analysis, the
component details are displayed.
The DCA Pro attempts to test the Zener diode with a current of nominally
5mA. For Zener diodes with a Zener voltage of more than about 7V, a lower
test current of 2mA or 1mA will be used. This is illustrated in the following
graph:
*The DCA Pro may not be able to identify Zener diodes with a Zener voltage
of more than 11V. It will however still identify the diode junction in its forward
biased mode.
