Tracing Modes Summary
The DIGICAT operates in the following modes:
• Power (Default Mode)
• Radio mode
• DIGITEX 8 kHz mode
• DIGITEX 33 kHz mode
• DIGITEX 33 kHz mode and depth measurements; only available with DIGICAT 200.
Frequency range: 50 Hz - 1.5 kHz
This is a passive mode – the signal, which the DIGICAT detects, is already present on the
service.
Used to trace live (energised) electrical power cables. Other services may emit power signals
due to currents flowing in them, such as metallic water pipes.
Frequency range: 15 kHz - 30 kHz
This is a passive mode – the signal, which the DIGICAT detects, is already present on the
underground service.
Used to trace metallic services, which may or may not have a power signal present. The radio
signal originates from powerful transmitters, operating at frequencies detectable by the
DIGICAT.
Frequency range: 8192 ± 30 Hz
This is an active mode – the signal, which the DIGICAT detects, must be impressed onto the
service by a DIGITEX.
Used to trace and identify metallic services, by impressing a distinct signal onto the service,
allowing it to be traced above ground. The 8 kHz signal provides minimum cross coupling
(leakage of signal from one service to another), when tracing in congested areas where
many services are present.
