Limitations of All Scan Mode
All Scan Mode has exactly the same limitations as those
listed for the Power and Radio Modes:
G
Street lighting cables when the lights are switched off,
supply cables to buildings or plant using little or no
electricity, pot-ended or capped cables, well balanced
high voltage cables and direct current cables may all be
missed on the All Scan Mode.
G
A strong All Scan signal present on one service may mask
a weaker All Scan signal present on an adjacent service.
G
It is not normally possible to determine what the service
is in All Scan Mode, only its position.
G
All Scan signals do not favour one utility over another.
G
The depth of the buried service CANNOT be judged by
the strength of the All Scan signal alone.
G
Normally it is only possible to detect All Scan signals
present on services up to 2 metres deep.
G
A short service may not have enough signal to be detected.
WARNING Using the Power and Radio Modes may be more effective in areas where there are many services
radiating an All Scan signal.
