  • Page 21: Null Mode

    Receiver 3.8.3 Null Mode This uses vertical antennas, and provides a minimum or “Null” response over the center of the buried line. The compass (line direction indicator) aligns itself parallel to the direction of the cable (available in Active modes) The null mode works well in uncongested areas but is more prone to inaccuracies due to the effects of field distortion.

  • Page 22: Omni Peak Response Mode

    When taking depth measurement, always hold the receiver at 900 to the ground. Alternative Locate Screens As previously mentioned, the vLoc3-Pro has a number of alternative screens. The following section describes operation these screens. It is left to the user to decide which is the best screen for a particular application.

  • Page 24 Receiver The cross-sectional section of the screen will respond as the target is approached. Use the + and – keys to alter the scaling if necessary. There is a black line leading from the locator to the target line. The target is represented by a blue dot. Around the dot is a circle, the size of the circle indicates a confidence factor.
  • Page 25 Receiver Using the Plan View screen. Apply the signal to the target line in the usual way and select the plan view screen by using long presses on the return button until the desired screen appears. Position the locator within the approximate position of the target line. Use the plan view to help guide you toward the target line.
  • Page 26 Receiver In non-distorted fields, the peak and null positions should coincide and the shape of the fields should be symmetrical about the center line. The picture below shows a slightly distorted field. 3’9” 33dB 14.1mA 8.19kHz To take a plot first locate the target using one of the other locate screens. Now select the Transverse screen by a prolonged press of the return button.

Passive locating refers to the process of detecting signals that “naturally” occur on pipes and cables. These tend to fall into two categories, radio signals and power signals.

  • Page 28: Detecting Power Signals

    Keeping the vLoc3-Pro vertical, walk across the area to be checked keeping the orientation so that the blade is in line with the direction of walking (See diagram above). If using the Onmi Peak mode the orientation of the locator is not important.

  • Page 29: Detecting Radio Signals

    Using the vLoc3-Pro Rotate the vLoc3-Pro on its axis to obtain the maximum signal. The vLoc3-Pro is now directly over the line and with the blade across the line. (If using the Omni-Peak mode there will be no change so switch to Peak mode if the direction is required).
  • Page 30 Using the vLoc3-Pro WARNING Only authorized personnel should make connections to cables. To make a direct connection, insert the direct connection connector to the transmitter. Insert the ground stake into the ground a few meters perpendicular to the line. Connect the black lead to the ground stake. Now take the red lead and connect to the target line.

  • Page 31: Signal Clamp (For Frequencies Above 8Khz)

    Using the vLoc3-Pro 4.3.2 Signal Clamp (for frequencies above 8kHz) In many situations, it is not possible to gain access to a cable to make an electrical contact. Or if there is, it is not safe to do so. The signal clamp provides an efficient and safe method of applying a locate signal to a cable.

  • Page 32: Induction (For Frequencies Above 8Khz)

    With no direct connection lead or signal clamp connected, the transmitter will automatically start to radiate a signal around the transmitter. These signals will penetrate the ground and couple onto buried lines. The signal will then travel along the line which can be detected with the vLoc3-Pro locator. Applying an induction signal to a line.

  • Page 33: Locating Active Signals

    It may be necessary to reduce the sensitivity to keep the bar graph on scale. This is normal and should be expected. Try to keep the vLoc3-Pro vertical and avoid swinging it as this may create false readings.

  • Page 34: Searching (Sweeping) An Area In The Peak Mode

    Using the vLoc3-Pro If the signal is not distorted, the position of maximum signal will coincide with the position as indicated by the arrows. If these two positions do not agree, it may be because there is signal distortion. Treat the results with caution.

  • Page 35: Depth & Current Measurement

    If the depth measurement feature is activated, it is possible to take depth measurement estimations. To take a depth measurement, first pinpoint the position of the line as above. Place the tip of the vLoc3-Pro on the ground making sure it is vertical and across the line i.e.

The sonde is located under the center of the “large peak” The vLoc3-Pro detects the presence of the two “Null” signals and also the position of the main “Large Peak”. It uses this information to provide a reliable and efficient method of sonde location.

  • Page 38: Signal Direction Precision Identification

    4.11 Signal Direction Precision Identification (Available for vLoc3-Pro with SD and vLoc3-ML 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 39 Using the vLoc3-Pro ● Turn the transmitter and receiver on, and set both to: ο SD-USA – if in North America or any territory where the power system is 60Hz. ο SD-EUR – if in Europe or any territory where the power system is 50Hz.

    In the case of cables, faults are usually caused by insulation damage allowing the metallic sheath (or internal conductor) to become in contact with the ground. It is intended to be used with the vLoc3-Pro range of locators and will require a fault find signal applied to the faulty conductor from a Vivax-Metrotech compatible transmitter.
  • Page 75 Using the Accessories Fault finding requires a non-standard signal “8kHz FF” (or FF fault find signal but ensure the Rx and Tx settings are matched). To detect a damaged section, the line should be isolated and have all ground bonding removed. This will ensure that the ground fault is not masked by deliberate bonding to ground.
