8.2.6: Conductive Plastic (AA) and Metal Probes (BB)
Two probes are provided with the HOUND 3. They are easily
changed by screwing and un-screwing them from the tip of
the HOUND 3.
The metal conical probe is rugged and durable. If working
with low voltage wiring, the metal probe can provide a sig-
nificant increase in signal loudness when the metal in the
target wire, or a metal contact connected to the target wire,
is touched. This sometimes aids in identifying the target wire.
For example, the metal probe is often used to drag along
the contacts on a telephone punchdown block. In situations
where the metal probe may short a circuit, leading to dis-
ruption of the circuit operation, or may short a power cir-
cuit, possibly causing equipment damage and user injury,
use of the conductive plastic probe is recommended. The
plastic probe is only slightly conductive, and usually causes
no disruption of equipment operation. An additional advan-
tage is its “duckbill” shape, which allows it to penetrate deeply
into a bundle of wires.
Helpful Hint
When using the conductive plastic probe, greater signal
pickup will be obtained if the wire being probed is laid against
the flat surface of the duckbill. Laying the wire against the
tip or edge of the duckbill will not produce the strongest
signal.
