Connecting to a service
Danger
To induce a signal into a service, place the DIGITEX over the service, with the arrows on the
top of the case pointing in the direction you believe the service is running, and turn it on.
The service can now be traced by the DIGICAT, providing both DIGICAT and DIGITEX are both
set to the same frequency (8 or 33 kHz).
This is the most efficient way of applying a signal to a service, and should be used whenever
possible. It is also the mode needed when any of the System accessories are used.
The connection lead should be plugged into the DIGITEX, the earth spike pushed into the
ground as far as possible from the DIGITEX, and at 90 degrees to the service to be traced.
Next the red lead is attached to the service, and the black lead attached to the earth spike,
ensuring the connections are as good as possible.
The DIGITEX audio tone will change from pulsed to continuous when a good connection is
made.
If this does not occur, it may be necessary to clean connection points with a wire brush or
sandpaper or improve the earth spike ground connection.
Pour water over earth spike if operating with dry soil conditions to improve connection.
The service can now be traced by the DIGICAT, providing both DIGICAT and DIGITEX are both
set to the same frequency (8, 33 or 8 and 33 kHz combined).
Connecting the lead set to a live service can result in receiving an electric shock.
Precautions:
The connection lead set should never be connected directly to a live service.
