Zener Diode Test
To perform zener diode test:
1
Turn the rotary switch to the
/
position.
2
Connect the red alligator lead between the positive output terminal and the
positive (anode) side of the zener diode. See
3
Connect the black alligator lead between the negative output terminal and the
negative (cathode) side of the zener diode.
4
Connect the red and black probe leads to the input terminals.
5
Output a constant current of
+
1 mA, then measure the forward voltage of the
zener diode.
6
Output a constant current of –1 mA, then measure the breakdown voltage of
the zener diode.
CAUTION
To avoid damaging the instrument, disconnect the circuit power and
discharge all high-voltage capacitors before testing the diodes.
