Page 18: Holding The Locator
Using the Locator: Holding the Locator Your middle or little finger should be used to squeeze, When in use the Locator should always be held upright. and hold on, the On/Off trigger. NEVER swing the Locator such that it moves away from the vertical. -
Page 19: Searching
Using the Locator: Searching There are three stages to the locating process; searching, pinpointing and tracing 1. Turn the Mode Switch to the appropriate mode. 2. Hold in the On/Off trigger. The Locator should emit the audible battery test tone and the digital display should come on. Check the battery level indicator to confirm the batteries are usable. -
Page 20: Pinpointing
Using the Locator: Pinpointing Having found a signal the next step is to pinpoint the source. The closer the Locator is to the signal source the stronger the response. To Pinpoint a Signal 1. Keeping the Locator vertical, walk through the area of the signal response. -
Page 21: Tracing
Using the Locator: Tracing Having pinpointed a service it should now be possible to trace its route. 1. Carefully follow the direction of the signal holding the Locator at right angles to the line of the signal. It is necessary to constantly ‘slice’ the Locator from side to side in order to be sure of still being over the peak signal response. -
Page 22: Using The Generator/ Transmitter Output Power
Using the Generator/ Transmitter: Output Power Level and Pulse/ Continuous Output Output Power Level The SGV2 Generator and the MXT2 Transmitter have four, selectable output power levels. The SGA2 Generator has two selectable output power levels. For long distance tracing or for detecting deep services it is always best to use the highest power setting of the Generator/ Transmitter. -
Page 23: Frequency
Using the Transmitter: Which Frequency Signal to use (MXT2 Transmitter only) Generally, Combined Frequency is the best frequency setting to use as it performs well in all applications. The lower frequency signals (8kHz and 640/512Hz) should travel further along a metallic service than the higher frequency signals although they may be more difficult to successfully apply in the first place. -

Page 25: Direct Connection
Using the Generator/ Transmitter: Direct Connection WARNING Never connect directly to electrical services. WARNING You may need to seek permission from the service owners before connecting on to some buried services. The Direct Connection Leads and Earth Stake that are supplied with the Generator/ Transmitter are used to apply a signal to any metal pipe at a suitable access point such as a valve, hydrant point, stop cock or exposed pipe length. - Page 26 Using the Generator/ Transmitter: Direct Connection 5. Connect the black Earth Lead to the Earth Stake (or the alternative earth point). If your earth point is too far away from the pipe access point for the black Earth Lead to reach then use the yellow 10 metre Auxiliary Earth Lead instead.

Page 27: Street Lighting/ Furniture
Using the Generator/ Transmitter: Direct Connection Direct Connection to a Street Lighting Column or other street furniture The best method to determine the position and route of street lighting, car park lighting cables or any other item of street furniture with a power supply is by using a Generator/ Transmitter and the pipe connection method. - Page 28 Using the Generator/ Transmitter: Signal Hopping Signal Hopping using Direct Connection Leads If it is difficult or inconvenient to use the Direct Connection method of signal application then an alternative technique called Signal Hopping can be utilised to successfully energise a street lighting or car park lighting cable with the Generator/ Transmitter signal.
-
Page 29: Signal Clamp/ Injector
Using the Generator/ Transmitter: Signal Clamp/ Injector Signal Clamp 1. Plug the Signal Clamp into the connection socket on the Generator/ Transmitter. 2. Turn the Generator/ Transmitter on (and select either CF or 8kHz on the Transmitter). 3. Check that the jaws of the Signal Clamp are clean. Place the Signal Clamp AROUND the cable making sure that the jaws are able to fully close. -
Page 30: Searching
Generator/ Transmitter: Searching for the Direct Connected Signal The search pattern used to find the Generator/ Transmitter signal when applied by a direct connection method (Direct Connection Leads, Signal Clamp or Signal Injector) is different to the normal search pattern used on Power, Radio or All Scan Modes. 1. -
Page 31: Tracing
Generator/ Transmitter: Tracing the Direct Connected Signal The tracing technique used to follow the Generator/ Transmitter signal when applied by a direct connection method (Direct Connection Leads, Signal Clamp or Signal Injector) is almost exactly the same as the normal tracing technique used on Power, Radio or All Scan Modes but with the following differences: The signal that the Locator is detecting will get weaker... -
Page 32: Induction
Generator/ Transmitter: Induction This is the standard method for inducing signals onto buried metallic services. It produces a strong signal directly below the Generator/ Transmitter but the signal strength drops off quite quickly either side of the Generator/ Transmitter. 1. Check that there are no accessories plugged into the Connection Socket. -
Page 33: Searching
Generator/ Transmitter: Searching for an Induced Signal The search pattern used to find the Generator/ Transmitter signal when applied by Induction Mode is slightly different to the search pattern used on other modes. 1. Move AT LEAST 10 metres away from the Generator/ Transmitter position with your Locator. - Page 34 Generator/ Transmitter: Searching for an Induced Signal 5. Walk in a straight line across the end line of the Generator/ Transmitter. When a signal is detected ‘pinpoint’ that signal as shown in the ‘Using the Locator’ section. If no signal is found move the Generator/ Transmitter 5 metres and try again.
-
Page 35: Multiple Services
Generator/ Transmitter: Induction; Multiple Services It is important to check for the presence of adjacent services running close, or parallel, to the service that you have already located. 1. Check that there are no accessories plugged into the Connection Socket. 2. -

Page 39: Sonde Batteries
Pipe Tracing using a Sonde: Batteries Duct Sonde The Duct Sonde is supplied at 33kHz only (yellow casing) and is powered by a single AAA (LR03) size alkaline battery. Rechargeable batteries are not recommended for this product. 1. To turn the Duct Sonde on, use a large flat bladed screwdriver to unscrew the battery cover located within the hollow end of the Sonde casing. - Page 40 Pipe Tracing using a Sonde: Tracing a Sonde The technique used to determine the position of a Sonde is always the same irrespective of which Sonde is being used. Before inserting the Sonde into the pipe it is best to set up the Locator so that the sensitivity is correctly adjusted to suit the pipe depth.
- Page 41 Pipe Tracing using a Sonde: Tracing a Sonde 3. Keeping the blade of the Locator in line with the Sonde, 3./ 4. move the Locator backwards and forwards over the length of the Sonde. Adjust the sensitivity until a clear peak response is shown on the display as the Locator passes directly over the position of the Sonde.
-
Page 42: Tracing
Non-Metallic Pipe Tracing: Plastic Pipe Tracer Line Tracing The Plastic Pipe Tracers can be used in services up to 3 metres deep (Locator dependent) on line tracing mode but cannot transmit through metal pipes or ducts. The Plastic Pipe Tracer needs to be inserted into the pipe before a signal from the Generator/ Transmitter is applied to the length of the Tracer. - Page 43 Non-Metallic Pipe Tracing: Plastic Pipe Tracer End Tracing The very tip of the Plastic Pipe Tracer can be energised with the signal from a Generator/ Transmitter. It is acting much like a Sonde and offers a very reliable way of pinpointing the position of the tip. A CF Generator/ Transmitter signal is applied by connecting the red Direct Connection Lead to one of the terminals on the Tracer and the black Earth Lead to the other terminal.

Page 44: Depth Measurement
Depth Measurement (DXL2 and MXL2 Locators only) The DXL2 and MXL2 Locator can be used in conjunction with the Generator/ Transmitter or Sonde to indicate the depth of a buried service. Depth cannot be measured on the Power, Radio or All Scan Modes. On the MXL2 Locator depth measurements can be taken from a CF, 8kHz or 640/512Hz signal. - Page 45 Depth Measurement (DXL2 and MXL2 Locators only) 4. Press and hold down the depth button. The depth will be shown on the display, measured in metres. 5. The depth can be verified by lifting up the Locator whilst keeping the depth button depressed.

Depth Measurement using Sonde/ Plastic Pipe Tracer (end tracing only) (DXL2 and MXL2 Locators only) NOTE The following instructions apply equally to the Plastic Pipe Tracer in End Tracing Mode, the Duct Sonde and the General Purpose Sondes. 1. Pinpoint the exact position of the Sonde as shown in the ‘Pipe Tracing using a Sonde’ section. Take care to ensure that you are over the top of the Sonde and not over one of the two ‘ghost’... - Page 47 Signal Current Measurement (MXL2 Locator only) MXL2 Locator only: Signal Current Measurement is a feature by which it is possible to measure the TRUE strength of the Generator/ Transmitter signal on a buried metal pipe or cable irrespective of its depth. This is a useful aid for the correct identification of specific pipes and cables and may also help to determine the layout and condition of a pipe or cable network.
- Page 48 Signal Current Measurement (MXL2 Locator only) Signal Current Measurement can also help to identify the layout of pipe and cable networks as the main line after a ‘T’ will have most of the Signal Current remaining on it whereas the shorter connection will have correspondingly less.
- Page 49 Signal Current Measurement (MXL2 Locator only) To ensure reliable Signal Current readings it is vital to adhere to the same best practises as are used to give accurate Depth Measurement readings. 1. Only apply the signal by a Connection method (Direct Connection, Signal Clamp or Signal Injector) to the target service.
