3. Follow step 2 and 5 as for resistance measurements.
4. An audible tone will sound for resistance less than approx. 50 Ω.
After all measurements are completed, disconnect the test leads
from the circuit and from the input terminals.

3. Follow steps 2 and 5 as for resistance measurements.
4. The red test lead should be connected to the anode and the
black lead to the cathode. For a silicon diode, the typical forward
voltage should be about 0,7 V or 0.4 V for a germanium diode.
5. If the diode is reverse biased or there is an open circuit the
display shows "OL".
