Locator Operating Modes:

All Scan Mode

Limitations of

All Scan Mode

All Scan Mode has exactly the same limitations as those
listed for the Power and Radio Modes:

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.

A strong

All Scan signal present on one service may mask

a weaker

All Scan signal present on an adjacent service.

It is not normally possible to determine what the service

is in

All Scan Mode, only its position.

All Scan signals do not favour one utility over another.

The depth of the buried service CANNOT be judged by

the strength of the

All Scan signal alone.

Normally it is only possible to detect

All Scan signals

present on services up to 2 metres deep.

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.
