Using the Transmitter: Which Frequency Signal to use

(MXT Transmitter only)

Generally, 33kHz is the best frequency 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 signal (33kHz) although they may be more difficult

to successfully apply in the first place. There should also be less

‘coupling’ of these signals onto adjacent services.

There are exceptions to this general rule and so the best option is

to try each frequency 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 as the Transmitter.
