3. At the target conductor, scrape away
any dirt, paint, corrosion, or other
coatings and attach the other cable
lead clip with either the teeth or the
magnet.
Good contact between the cable lead
and the target conductor lowers the
resistance of the circuit and produces
a stronger tracing signal.
Note: Non-conductive pipes, such as
those made of clay or plastic, cannot
carry a tracing current without a trace
wire. Plastic pipes typically have a
trace wire installed with the pipe for
tracing purposes. Clip the cable lead
to the trace wire to enable tracing.
Expanded Frequency Settings
While in Direct Connect Mode, the transmit-
ter can be used with high or dual frequen-
cies.
1. Long press (>3 seconds) the Fre-
quency key
to high frequency.
2. Short press the Frequency key
cycle through dual frequency options
or return to the high frequency. Ex-
panded frequency options include:
• 262 kHz or 93 kHz only.
• 33 kHz and 1 kHz dual frequency
transmission.
• 33 kHz and 8 kHz dual frequency
transmission.
The LED associated with each fre-
quency is lit when that frequency is
in use.
3. Long press the Frequency key
again to return to standard frequency
options.
Note: High frequency is 93 kHz or 262 kHz
depending on your region. Expanded fre-
quency settings are only available in Direct
Connect Mode.
