Using the Transmitter:
Which Frequency Signal to use
(
MXT2 Transmitter only
)
Generally, Combined Frequency is the best frequency setting to use as it
performs well in all applications. The lower frequency signals
(
8kHz and
640/512Hz
)
should travel further along a metallic service than the higher
frequency signals although they may be more difficult to successfully apply
in the first place. There should also be less ‘coupling’ of these lower
frequency signals onto adjacent services.
There can be exceptions to this general rule and so the best option is to
try each frequency setting and then utilise the one that is giving the best
results for that particular service. This is irrespective of the method of
signal application; Direct Connection, Signal Clamp, Signal Injector or
Induction Mode, and of the service being traced.
NOTE
The 640/512Hz frequency signal can only be applied using the Direct Connection Leads and with a
Continuous signal output.
WARNING
The Locator frequency MUST always be set to the same frequency setting as the Transmitter.
