8. OPERATING INSTRUCTIONS
8.9 DIODE - FIGS. 10 - 11
The diode work mode is to test the polarity of PN junction of
diode. Contact the probe and the black alligator clip to two
electrodes of diode. After getting the result, exchange the
position of probe and the black alligator clip to get the other
result. One of the results will have relatively larger
resistance value or infinite value (Reverse Conduction), the
other one will have smaller resistance value. (Forward
conduction) In the measurement result with smaller
resistance value, it is the anode that the probe is contacted
to; the black alligator clip is contacted to the cathode of
diode. If the resistance value in both measurements is
shown as “0.0Ω”, it means the diode is broken down and
damaged.
