2 Description of the System

2.1 System Information

General description

Locators are used to detect buried conductive utilities that emit an electromag­netic signal. Such a signal is generated as an electrical current passes through
the utility.

Signal transmitters are used to apply a distinct signal to utilities with the fol­lowing intention:

•

To improve the detection success.

•

To trace the route of a utility.

•

To make a depth or current measurement.

Accessories are used with the locator and transmitter to localise the position
of utilities, including some that are non-metallic.

The locators and transmitters described within this manual greatly facilitate the
search process and help to reduce the dangers and costs associated with utility
strikes. However, electromagnetic location depends on the utilities being con­ductive (metallic) and emitting a signal as current passes through them.

䖾

Keep in mind that a locator on its own cannot detect all utilities. Take
care when excavating. We recommend that you adopt a safe system
which includes the planning of the search process in advance, the use
of utility maps, the use of locators and transmitters, and the use of
safe digging practices.

3.5 Search Modes

Available search
modes

Search Mode Description

Auto mode Combined detection of Power and Radio modes.

䖾

This mode facilitates a one-step sweep
search process.

Power mode This mode is used to detect electrical cables.

䖾

Radio mode This mode is used to detect metallic pipes or cables,

including telecoms and electrical.

䖾

Power mode is dependent on an electrical
current flowing through a cable. Keep in
mind that not all electrical cables carry a
detectable signal and thus pose a serious
risk, for example supplies to unilluminated
street lights, unoccupied buildings or bal­anced three-phase cables.

Radio mode is dependent on reradiated
radio waves originating from radio masts.
Keep in mind that signal availability can
vary or be restricted depending on factors
including line of site, signal application or
routine mast maintenance.

Search Mode Description

Signal Transmitter
mode

Used in conjunction with a signal transmitter:

•

To improve the detectability of utilities.

•

To trace a specific utility.

•

To make a depth or current measurement.

䖾

•

•

•

•

Example:
A 131 kHz frequency has a greater ability to couple
onto other utilities, jump over insulated pipe joints,
travel down small-diameter cables or pot-ended (ter­minated) cables.

•

•

•

䖾

•

•

Keep in mind the following:

Higher frequencies couple onto utilities more
easily than lower frequencies.
Higher frequencies travel shorter distances; the
higher the frequency the less the distance trav­elled.
Higher frequencies are likely to couple onto
other utilities; the higher the frequency the
greater the spread.
Higher frequencies are useful for avoidance
activities.

To trace the route of a pipe or duct, including
non-metallic variants.
To locate a blockage or collapse.
To make a depth measurement.

Keep in mind that various sondes are avail­able for specific task-based applications:

Sondes with higher frequencies are used for
generic pipe or duct tracing.
Lower frequencies (512 Hz, 640 Hz) work best
for metal pipes.

WARNING

The absence of a positive indication does not guarantee the non-existence of a
utility.
Utilities without a detectable signal may be present.
The locators can only locate non-metallic utilities such as plastic pipes, typically
used by the water and gas utilities, with the use of appropriate accessories.

Precautions:

▶

Always excavate with care.

5.4 Using the Transmitter in Induction Mode

5.4.1 General Information

Induction mode

Induction is a quick and simple way to apply a signal to a utility without the
need to make any physical connection to it. The transmitter uses an internal
aerial to transmit the signal to the utility.

䖾
䖾

䖾

䖾

250 425

13278_001

Work at least 10 m/33 ft away from the transmitter to avoid airborne
signals. Reposition the Transmitter if necessary.

Coupling efficiency is best at 33 kHz.

The signal can also apply itself to other utilities within close proximity
to the transmitter, depending on their depth and direction.

To increase the battery life and to reduce the possibility that the sig­nal is applied to adjacent utilities, reduce the signal output.

The Numeric Peak Indicator can be used to indicate multiple utilities
or to assist tracing. The utility with the maximum value is typically the
one closest to the transmitter or the one directly connected to.

Standard process for
Induction mode

5.5 Using the Transmitter in Connection Mode

5.5.1 General Information

Connection mode

Connection mode is the most efficient way to apply a signal to a utility. The
cable set of the transmitter or any of the available accessories are connected
to the utility which is to be traced or identified.

䖾

䖾

䖾

䖾

䖾

Whenever possible, use the transmitter in connection mode, espe­cially for taking a depth reading.

The Numeric Peak Indicator can be used to indicate multiple utilities
or to assist tracing. The utility with the maximum value is typically the
one connected to.

The black connection cable can be connected to other metallic struc­tures which go into the ground, such as iron grids or metal covers of
access chambers.

In dry conditions it may be necessary to add water around the earth
point to get a good connection.

When using the connection cable set, examine the connection points
and remove contamination if a continuous audible output is not ach­ieved.

42 Applications

Find Quality Products Online at: [e-mail]

www.GlobalTestSupply.com

䖾

䖾

An extension cable is available to extend either the red or black cables
on the connection cable set.

Reducing the signal output helps to extend the battery life and to
reduce the amount of signal applied to adjacent utilities.

5.5.2 Direct Connection Mode

Using the transmitter
in Direct Connection
mode

1. Plug the transmitters cable set into the
connection socket.

2. Ensuring that no utilities are below, push
the Earth Pin into the ground and con­nect the black cable to the Earth Pin.

䖾

䖾

3. Connect the red cable to the utility.

䖾

䖾

䖾

For more safety, we recom­mend pushing the Earth pin
into the ground at an angle of
45 degrees.

For best performance, position
the Earth pin and black cable
at 90 degrees to the suspec­ted direction of the utility.

Never connect the red cable
directly to an electrical cable!

Connecting the red cable to
the metal framework of earth­bonded electrical installations
such as street lights, pumps or
motorised gate housings,
improves the detectability of
low-loaded electrical cables.
For best performance, connect
to bare metal.

Using the combination of
33 kHz and 131 kHz frequen­cies can improve the detecta­bility of small diameter cables
or their short runs.

The Current measurement is measured in mA (milliampere) and is dis­played with the utility line depth. Refer to "6.1 Utility Line Depth".

Identifying a utility

The signal transmitter is used to apply a signal (current) to the utility to be
traced. The signal can couple onto additional utilities making it difficult to dis­tinguish by conventional locating techniques.

Current measurement helps to identify the utility to which the transmitter is
attached by providing the highest current reading (mA). Unlike the Numeric
Peak reading, the current reading is not effected by changing depth levels.

9 Batteries

䖾

Use the locators and transmitters with an authorised rechargeable Li-Ion bat­tery pack.

9.1 Operating Principles

First-time use/
charging batteries

Operation/
discharging

•

The battery must be charged before using it for the first time because it is
delivered with an energy content as low as possible.

•

The permissible temperature range for charging is from 0 °C to +40 °C/
+32 °F to +104 °F. For optimal charging, we recommend charging the bat­teries at a low ambient temperature of +10 °C to +20 °C/+50 °F to +68 °F
if possible.

•

It is normal for the battery to become warm during charging. Using the
chargers recommended by Leica Geosystems, it is not possible to charge
the battery once the temperature is too high.

•

For new batteries or batteries that have been stored for a long time
(> three months), it is effectual to make only one charge/discharge cycle.

•

For Li-Ion batteries, a single discharging and charging cycle is sufficient. We
recommend carrying out the process when the battery capacity indicated
on the charger or on a Leica Geosystems product deviates significantly
from the actual battery capacity available.

•

The batteries can be operated from −20 °C to +55 °C/−4 °F to +131 °F.

•

Low operating temperatures reduce the capacity that can be drawn; high
operating temperatures reduce the service life of the battery.

9.2 Charging the Li-Ion Battery Pack

WARNING

Short circuit of battery terminals

If battery terminals are short circuited e.g. by coming in contact with jewellery,
keys, metallised paper or other metals, the battery can overheat and cause
injury or fire, for example by storing or transporting in pockets.

Precautions:

▶

Make sure that the battery terminals do not come into contact with metal­lic objects.
