Depth Measurement
The Loki receiver will automatically measure and display the depth in Power,
Transmitter and Sonde modes.
Note: The Loki receiver does not measure depth in Dual mode.
Method: Locate the utility as follows. Hold the Loki receiver still and vertically cen-
tred above the detected line and across the line of the pipe/cable.
Note: A depth measurement will not be displayed where environmental conditions
are poor (e.g. weak signal or interference).
The measurement is to the centre of the pipe/cable or to the centre of the sonde,
which may rest at the bottom of the pipe.
Do not use the depth measurement function to decide if mechanical digging is
appropriate.
Noise
Protect
™
All Loki receivers incorporate Noise
Protect™
, a powerful signal-processing tool
that identifies and automatically rejects electrical interference that may otherwise
overload the Loki receiver’s electronics. Noise
Protect™
allows the operator to
locate pipes and cables in electrically noisy environments such as near power
sub stations or near overhead high-voltage cables. Note that Noise
Protect™
will
not overcome very high levels of interference. In this situation the Signal Overload
Warning will appear (see Warnings).
Shallow
Alert™
The Shallow
Alert™
feature warns the operator of shallow pipes and cables.
When a shallow cable or pipe is detected (in any mode). Shallow
Alert™
flashes
an asterisk and sounds a distinctive warbling audio tone.
