reverse bias test. Overload indicates a good diode.
Note 1: Overload condition for both reverse and forward bias tests indicate an
open diode. A low voltage reading for both bias tests indicates a shorted diode.
If the diode is shunted by a resistor of 1000 ohms or less, it must be removed
from the circuit before taking the measurement. Bipolar transistor junctions
may be tested in the same manner described above.
