Testing a Diode or a Diode Wire
A diode wire is a diode with male connector fitted on one end and a female connector fitted on the other end. The diode is
sealed in heatshrink sleeving.
On the AV0 2003
Move the right hand slider to position A, and the left hand slider switch to position C.
Connect the black probe to the end of the diode marked with a band, or to the male connector of the diode wire, the red probe
should be connected to the other end of the diode or diode wire. If the Avometer does not buzz the diode is faulty.
Connect the red probe to the end of the diode marked with a band, or to the male connector of the diode wire, the black probe
should be connected to the other end of the diode or diode wire. If the Avometer does not read "1" the diode is faulty.
On an analogue meter
Select the Ohms 1000s (1k) range.
Connect the black probe to the end of the diode marked with a band, or to the male connector of the diode wire, the red probe
should be connected to the other end of the diode or diode wire. The meter should read 20-400 K , if it reads more than this
the diode is faulty.
Select the Ohms 100s range.
Connect the red probe to the end of the diode marked with a band, or to the male connector of the diode wire, the black probe
should be connected to the other end of the diode or diode wire. The meter should read 300-400 , if it reads less than this the
diode is faulty.
