Page 69: Passive Or Active Location
Using the vLocPro2 Using the compass (line direction indicator) to locate the Sonde requires free space to walk to the side of the Sonde. If there is an obstacle such as a wall or vehicle that restricts walking in an arc, the following method can be used. -
Page 70: Active Locating
Using the vLocPro2 Passive location is used to search an area to see if buried metallic lines are present (known as locating to AVOID). It does not help to identify what buried pipe or cable is present, only to confirm that there is a pipe or cable there. -
Page 71: Clamp (Coupler)
Using the vLocPro2 WARNING Never make a direct connection to live cables carrying hazardous voltages. Do not plug the connection leads into the transmitter before connecting to the buried line and fixing the ground stake. Take the ground stake and push firmly into the ground and connect it to the black connection lead. -
Page 72: Induction
Using the vLocPro2 Do not plug the clamp into the transmitter before applying it to the target line. Open the jaws of the clamp, place around the target line, close the jaws. Be sure that the jaws of the clamp are completely closed. -
Page 73: Searching (Sweeping) An Area
Using the vLocPro2 When using the “Induction” mode to apply a signal to a line, ensure that a minimum distance of 50ft (15m) is maintained. This is because the transmitter will transmit signal through the air which will interfere with signals from the cable, resulting incorrect information. -
Page 74: Pinpointing & Confirming The Buried Line
Using the vLocPro2 9.5.1 Pinpointing & Confirming the Buried Line Marking the exact position of the buried line is generally called pinpointing. Pinpoint the line before marking its position. Place the receiver in “Peak” or “Left/Right” mode, pass the blade of the receiver across path of the cable and identify the peak response on the display and/or audibly. -
Page 75: Measuring Depth And Current
Using the vLocPro2 • Measure the depth of the buried line by pressing “i” pushbutton briefly to measure depth and current. The depth should be approximately in line with the “as built” plans available. If no plans are available logic would still help to assess the situation (if you are looking for a CCTV distribution cable and the depth indicated is 5ft (1.5m) it is probably not your cable). - Page 76 Using the vLocPro2 Distance A to B = Depth (D) Distance (A’ to B’)/2 = Depth (D) Semi Automatic Triangulation Mode On some models a "triangulation mode" is available that assist in taking these types of measurements. To use the Triangulation mode the function must first be activated in the User Menu. The User Menu will give the option of Peak Depth or Triangulation.

Page 77: Signal Direction Precision Identification
9.7 Signal Direction Precision Identification (Available for vLocPro2-SD and vLocML2 models only) Some models in the vLoc series of locators contain a feature called “SIGNAL DIRECTION”. This feature is used to verify if the line being located is the target to which the transmitter has been connected. - Page 78 Using the vLocPro2 ○ SD-USA – if in North America or any territory where the power system is 60Hz. ○ SD-EUR – if in Europe or any territory where the power system is 50Hz. • The receiver may, or may not be flashing the “SD” icon and compass (line direction indicator) bezel.
- Page 79 Using the vLocPro2 • Re-trace your line back to a point where a solid signal direction is obtained. Precisely pinpoint the line and stand with your back to the direction of the transmitter as you did when you initiated the original sync, and press the “i” pushbutton then the enter/return pushbutton to re-sync with the transmitter signal.

Page 80: Using The Accessories
Using the vLocPro2 Using the Accessories 9.8.1 Using the LPC Separation Filter The LPC separation filter (LPC) is used to safely inject a trace tone to a live cable via a domestic mains socket, so that the cable can be traced from the premises to the connection in the street. It is suitable for connecting to voltages between 100V AC and 250V AC. - Page 81 This will ensure that the ground fault is not masked by deliberate bonding to ground. The A-frame cannot distinguish between these two situations. After isolating the line, use the vLocPro2 transmitter resistance measuring function, or a dedicated resistance measuring device to confirm that there is a fault to ground. The A-frame will typically detect faults up to two Mohm and above (depending on the distance from transmitter, soil conditions etc).
- Page 82 Using the vLocPro2 Remove the plastic spike covers from the A-frame. Walk along the route of the line placing the spikes of the A-frame in the ground (with the green leg pointing away from the transmitter connection point) every two or three paces. If starting near the transmitter, the arrow on the display will point away from the ground point.

Page 83: Using The Analogue Remote Antenna
Using the vLocPro2 9.8.3 Using the Analogue Remote Antenna The remote stethoscope antenna can be used to help identify a particular cable on a cable tray or where cables are bunched together. Methods: 1. Connect a signal to the cable to be identified. The remote stethoscope functions has an operational frequency range of 512Hz up to 200 kHz, but low frequencies should be a preference in this application as they are less likely to leak or bleed over to other cables. - Page 84 Using the vLocPro2 6. Connect the remote stethoscope antenna to the accessory input of the receiver. The correct settings and user interface will be automatically selected. 7. Ensure the frequency selected on the vLoc is the same as selected on the transmitter.
- Page 85 3. At the point of interest, run the remote stethoscope antenna along the suspected target cable. If the correct cable is being assessed the signal will increase and decrease in sympathy with the twist of the two conductors within the cable. 4.
- Page 86 2. Select an SD signal from the transmitter (either SD-USA or SD-EUR). 3. Connect the remote antenna accessory to the locator and place it on the red lead of the transmitter with the arrow pointing away from the transmitter. Select the frequency using the “f” button so that it matches the selection on the transmitter.
- Page 87 The system is now ready to identify the cable at the location of the interest. Identifying a cable Having confirmed the antenna is synchronized with the receiver, proceed to the location the cable is to be identified. Place the antenna on each of the suspected cable in turn ensuring the correct orientation, ie the arrow on the antenna pointing away from the transmitter.
- Page 88 WARNING The remote stethoscope antenna is a useful tool to help identify cables. However, it should not be used as positive identification before an unused cable is cut. Always follow company procedures when cutting disused or isolated cables. Page 82 of 90...
