Note
：
When measuring at Range 200Ω, please short-circuit the test leads at
first to test the wire resistance, and then deduct it from the actual
resistance.

terminal (the polarity of red lead is “+”)
2. Turn the knob to
range ,press “SELECT” button to select the
Diode measurement mode.
3. Forward Measurement: connect test leads with the diode under tested,
the red test lead connect to diode positive polarity, the black test lead to
diode cathode polarity, the reading is the approx. value of diode forward
volt drop
.
4. Backward Measurement: the red test connect to diode positive polarity,
the black test lead to diode cathode polarity ,the LCD displays “OL”.
5. The complete diode testing includes forward and backward
measurement, if the result isn’t meet the above, it means the diode is bad.
