Get to know the DIGICAT
Ensure the DIGICA is func-
tioning correctly.
Practise over known under-
ground services if neces-
sary.
Ensure all users are fully
conversant with its opera-
tion.
he following is a suggested best
practise procedure for using the
DIGICA
Examine the area.
Obtain Utility drawings and
other relevant information
(if available).
Examine the area for evidence
of recently installed services.
Test that the DIGICAT is func-
tioning correctly.
Mark out the area to be sur-
veyed/excavated.
Make sure you are fully con-
versant with the DIGICA
and all its functions.
Thoroughly sweep the area in
both power and radio modes.
Use a signal generator (e.g.
DIGITEX 8/33) whenever
possible.
Use the DIGICAT in the trench
to check for further under-
ground services after excavat-
ing approx. 0.3m.
WARNING:
The absence of a positive
indication does not guarantee
the non-existence of a service.
Precautions:
Always excavate with care.
CAU ION:
The product cannot be used to
locate non-metallic services
such as plastic pipes typically
used by the water and gas
utilities.
Precautions:
Always excavate with care.
CAU ION:
The product may not find cer-
tain services.
Precautions:

Basic Overview
DIGICAT Start Up Test
This is best done in an area free of underground services. Hold the
DIGICAT vertically upright press and hold the yellow on/off trigger. The follow-
ing test sequence will take place.
ON TEST TEST PATTERN
Audio Output On throughout test sequence
Meter display LED’s scroll through in sequence (once)
Mode selection indicator LED’s scroll through in sequence
Battery low indicator Illuminated throughout test sequence
The unit will automatically select Power
mode and maximum sensitivity.
Walk into the area in which you wish
to search for underground services.
Ensure that the DIGICAT is held in an
upright position and as close to the
ground as possible. Sweep across
the area with the DIGICAT taking care
not to swing it - i.e. keep it vertically
upright and perpendicular to the
ground. In the presence of a live
electrical conductor (underground
service) a tone will be emitted and the
meter display will rise and fall as you
pass over the service.
The service is directly below the
DIGICAT when the meter display is at
its maximum reading.
The meter display does not
indicate the size depth or
electrical power strength of a
service.
Defining the exact position of an
unknown underground service is not
generally required. However if
greater accuracy is required use the
pinpoint method – detailed below.
o pinpoint the service (for greater
accuracy)
Position the DIGICAT directly over the
service. Press the up or down button
on the display panel to activate the
pinpoint facility. A second flashing
LED will be displayed below the
present meter display level. An au-
dible response will be emitted when
the constant meter display is above
the flashing LED. The up or down
buttons can be used to re-position the
flashing LED to give the required
audible response over the service.

Tracing Modes Summary
The DIGICAT operates in the follow-
ing modes -
Power.
Frequency range (50-60Hz).
This is a passive mode – the signal
which the DIGICAT detects is already
present on the service.
Used to trace live (energised) electri-
cal Power cables. Other services may
emit power signals due to currents
flowing in them such as metallic
water pipes.
Radio.
Frequency range (15-30KHz).
This is a passive mode – the signal
which the DIGICAT detects is already
present on the underground service.
Used to trace metallic services which
may or may not have a power signal
present. The radio signal originates
from powerful transmitters operating
at frequencies detectable by the
DIGICAT.
Generator 8 kHz.
This is an active mode – the signal
which the DIGICAT detects must be
impressed onto the service by a sig-
nal generator or transmitter such as
the DIGITEX 8/33.
Used to trace metallic services by
impressing a distinct signal onto the
service allowing it to be traced above
ground. The 8KHz signal provides
minimum cross coupling (leakage of
signal from one service to another)
when tracing in areas where many
services are present.
Generator 33 kHz.
This is an active mode – the signal
which the DIGICAT detects must be
impressed onto the service by a sig-
nal generator or transmitter such as
the DIGITEX 8/33.
Used to trace metallic services by
impressing a distinct signal onto the
service allowing it to be traced above
ground. The 33KHz signal provides a
greater locating range than 8 kHz but
with increased cross coupling (leak-
age of signal from one service to
another).
Tracing Modes Summary

DIGICAT

The DIGICAT locator detects the
electromagnetic field which is emitted
by metallic underground services.
The Digicat converts the electromag-
netic field into an electrical signal
which then informs the user of the
results of the detection via the Display
Panel.
Different types of underground ser-
vices emit different types of signals.
Some signals are already present on
the service and can be readily de-
tected by the DIGICAT. We call these
passive signals.
Some metallic underground services
do not emit signals. These services
may be traced by applying a signal to
the service using a generator or trans-
mitter such as the DIGITEX 8/33.
The DIGICAT has been designed to
be very user friendly.
It is simple to use in many tracing
situations without requiring highly
trained operators.
Although the DIGICAT is a
powerful tool there is no sub-
stitute for having diagrams
drawings and other information
about the area about to be
traced.

Although the DIGICAT can be used
with any locator that operates at 8 or
33 kHz it was designed to comple-
ment the DIGITEX 8/33 Signal Trans-
mitter with its dual frequency modes.
Function check
This is done to ensure the
DIGICAT and
DIGITEX 8/33 are functioning
correctly and are operating at
the same frequency.
Switch on the DIGITEX 8/33 select
the required frequency and verify the
mode and output displays.
Ensure that the DIGITEX 8/33 is in
Induction mode (there should not be a
plug in the connection socket).
Power up the DIGICAT and select the
same frequency as the
DIGITEX 8/33 is operating at.
Bring the DIGICAT to within 2 metres
of the DIGITEX 8/33.
The meter display on the
DIGICAT should indicate an
output from the
DIGITEX 8/33. If it does then
the system is functioning cor-
rectly.

Remove the batteries if the tool
is to be stored for longer peri-
ods of time. Avoid extreme
temperatures that can cause
battery degradation and early
failure of the batteries.
ransport
Although the DIGICAT is ex-
tremely robust is prudent to
ensure that the tool is trans-
ported in such a way as to
prevent damage. Never trans-
port the tool loose inside the
vehicle. Blows and vibrations
can damage the tool. It must
always be properly secured
within the vehicle.
When returning to Laser Align-
ment or one of their dealers for
service by road rail aircraft or
ship use the original packag-
ing (shipping box) where pos-
sible if not use other suitable
packaging securing the tool
against blows and vibrations.
You must remove the batteries
(send the tool without batter-
ies).
Cleaning
Use warm water and mild
detergent to clean the exterior
of the DIGICAT.
Do not use other cleaning
agents as the plastic parts or
labelling could be affected.
Wipe off splashes of cement
plaster etc. as quickly as
possible using water and a
damp cloth or sponge.
he DIGICA contains static sensi-
tive components
Do not attempt any internal repairs on
your unit. Opening the sensor will void
the warranty.
Servicing
Laser Alignment recommends that the
DIGICAT be returned to them or one
of their authorised service centres to
checked and calibrated annually.
Storage
When storing the equipment
particularly in summer and
inside a vehicle take the tem-
perature limits (-40°C to
+70°C / -40°F to +158°F) into
account.
If the tool has become wet dry
off the tool and accessories (at
maximum 40 ºC / 108ºF) and
clean.
After longer periods of storage
or transport carry out a func-
tional check before using the
equipment.
