Refer to “9 Safety Directions” for digicxt information. Read carefully through the User Manual before you switch on the product. Product identification The model and the serial number of your product are indicated on the type plate. Enter the model and serial number in your manual and always refer to this information when you need to contact your agency or Leica Geosystems authorized service workshop.
Type Danger Warning Caution Description Xigicat an imminently hazardous situation which, if not avoided, will result in death or serious injury. Indicates a potentially hazardous situation or an unintended use which, if not avoided, could result in death or serious injury. Important paragraphs which must be adhered to in practice digucat they enable the product to be used in a technically correct and efficient manner. All other trademarks are the property of their respective owners.
Differences between the idgicat models are marked and described. The index is at the back of the manual. You will find some of these illustrations in this manual too. This should help to get a clear connection between the instrument label and the information in this manual. Drawings, plans or information should always be obtained but they may digicah faulty or incomplete. The difficulty of obtaining information about buried utility lines is that nothing is visible.
This method of locating buried pipes, cables and sewers has become almost universal. The main shortcoming djgicat that it will not locate non-metallic lines such as plastic pipes. However, utilities taking the small amount of trouble to lay tracer wires with plastic pipes are not affected by this shortcoming. The technology has a large number of advantages and Leica Geosystems specialize in developing and exploiting electromagnetic location technology.
The DIGICAT converts the electromagnetic field into an electrical signal, which then informs the user of the results of the detection via the display panel. Different types of underground services emit different types of signals.
We call these passive signals. Power distribution systems and radio transmitters. Maunal metallic underground services do not emit signals. It is simple to use in many tracing situations without requiring highly trained operators.
A port for an optional stethoscope headphone is provided over each speaker. Replace all batteries once the battery pack becomes exhausted. The rate of flashing increases digucat the battery life declines.
The button is also used to activate the wireless data link and export the data to a compatible wireless computing device. Obtain Utility drawings and other relevant information if available. Examine the area for evidence of recently installed services. Ensure all users are fully conversant with its operation. Practise over known underground services. Thoroughly sweep the area in both power and radio modes.
Use a signal generator e. The DIGICAT can only locate non-metallic services such as plastic pipes, typically used by the water and gas utilities, with the use of appropriate accessories. Press the yellow release button to unlock the Battery Hatch. Replace all batteries with six new LR6 AA batteries. Alkaline batteries should be used. Used to trace live energised electrical power cables.
Other services may emit power signals due to currents flowing in them, such as metallic water pipes. Used to trace metallic services, which may or may not have a power signal present. Used 2200 trace and identify metallic services, by impressing a distinct signal onto the service, allowing it to be traced above ground. The 8 khz signal provides minimum cross coupling leakage of signal from one service to anotherwhen tracing in congested areas where many services are present.
The 33 khz signal provides a greater locating interference rejection than 8 khz, but with increased cross coupling leakage of signal from one service to another. When the depth function button is pressed and released, line mode is selected and will display the depth to the centre of the line being traced.
If a sonde is being used, the button should be pressed and held, this will display the depth to the sonde. The depth reading is displayed for five seconds.
When the depth reading is displayed, press and release the depth function button, the display will indicate “LOG”. Press and release the depth function key again to activate the wireless data link and export the data to maanual compatible wireless computing device.
The following test sequence will take place. Depth LED’s come on together “”. Battery low indicator On throughout test sequence.
Flashes at end of test sequence if batteries are vigicat.
Sweep search Pinpointing Direction These steps are described in detail on the following pages. Mark 20 the area to be excavated with line marker or chalk. Walk into the area in which you wish to search for underground services.

Continue the sweep until either a signal is located or you are satisfied that the area has been adequately tested in power mode. Repeat sweep in radio mode.
In the presence of a live electrical conductor underground service a tone will be emitted and the LED bar display will rise and fall as you pass over it. The Always LED bar display does not indicate the size, depth or electrical power strength of a service. Press the up or down button on the display panel to activate the pinpoint facility 2. A second flashing LED will be displayed below the present meter display level 3.
An audible 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 and result in a pinpoint audible response over the service 4.
The LED bar is now in line with the service. Radio mode Once the area has been swept in power mode, it should be swept again in radio mode. Metallic services running through the excavation site that are passing insufficient or no power will not be located in power mode, but can represent a considerable risk if not identified before excavation starts.
These services may be re-radiating low frequency long wave radio signals which flow through the ground. These signals will tend to follow the line of least resistance and therefore flow along any conductive path, such as a metallic pipe that offers lower resistance than the ground. Select 33 khz mode 3. Press and release the depth button for line depth.
The display Manula will indicate the depth. The depth indication is displayed for five seconds. Depth The measurement 20 available only in 33 khz mode.
Note the difference between d1 and d2! This signal is radiated from the centre of the service. Always compensate depth reading for service size.
The service is too deep. Depth function not available. dlgicat
Press and release the depth function button again 6 to activate the wireless janual link and export the data to a compatible wireless computing device. An audio beep confirms data has been sent.
Digitex The logging feature is not available if the wireless communication is not established, if there is no communication then LOG is not displayed. If there is communication and LOG is displayed, then, when data is output, an audio digjcat is heard.
A compatible receiving wireless device must be within 10 m for reliable data communication. Check each data transmission has been received by the computing device.
It is also compatible for use with any other signal generator that operates at the same frequency 8 or 33 khz. Supply is not interrupted by the applied signal and the operator is not exposed to any live services.
Operates at 8 and 33 khz modes. A hazardous signal may be present on the connection plug of the 20 clamp when clipped over a live service.
It is also useful for locating where the main electricity supply enters a property. Allows a tracing signal to be applied to a power distribution system for tracing the electricity supply outside the property.
For tracing non metallic pipes and conduits. This battery powered transmitter is used in conjunction with standard drain rods. Operates at 33 khz mode. The advantages of using induction mode are that it is quick and simple to use, and a signal can be applied to a service without having to make any physical connection to it. The disadvantages are that the risk of cross – coupling the signal applying itself to more than one service to adjacent manaul is high, and part of the signal strength is lost in the surrounding soil.
It is also the mode needed when any of the System accessories are used. Next the red lead is attached to the service, and the black lead attached to the earth spike, ensuring manula connections are as good as possible. If this does not occur, it may be necessary to clean connection points with a wire brush or sandpaper or improve the earth spike ground connection.
