    2.1.1 Alkaline Batteries The vScan requires six AA type alkaline batteries. To replace the batteries, unscrew the ¼ turn fastener of the battery compartment and open the internal battery door. Remove the battery holder and replace all the batteries. Mixing good and discharged batteries may result in excessive heat or even fire.

These warning icons will continue to be displayed until the relevant action is taken. If desired, the MyvScan desktop application can be used to configure these warnings so that if no action is taken the unit will shut down.

  • Page 16: Detecting Radio Signals

    4.2.1 Detecting Radio Signals Switch on the vScan receiver and select Radio mode using the mode paddle. Hold the vScan vertically and away from likely positions of cables or pipes. Adjust the sensitivity control so that the bar graph reading is just starting to show some movement. The sensitivity control should be at or close to maximum sensitivity.

  • Page 17: Detecting Power Signals

    If at any time, the meter reading starts to increase, carefully move the locator forward and back to detect the maximum signal. Use the peak level indicator to help confirm the correct position. Rotate the vScan on its axis to obtain the maximum signal. The vScan is now directly over the line and with the blade across the line.

  • Page 18: Active Locating

    To inject a signal requires the use of the vScan transmitter. The signal can be injected, or applied, to the target line in a variety of ways.

  • Page 19: Signal Clamp

    Locating When connecting to a ferrous material, it is sometimes not possible to find a suitable projection to apply the connection clip. If this is the case, use the magnet supplied to make contact to the line and then clip the red clip to the magnet. A good example of this is to make a connection to a street lighting circuit.

  • Page 20: Induction (33 Khz)

    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 vScan locator. Applying an induction signal to a line.

  • Page 21: Detecting Active Signals

    Move the locator backward and forward to ensure a maximum signal is detected. Use the peak level indicator to assist. With the maximum signal found and the compass running across the bar graph, the vScan is now directly over the line and exactly across it.

  • Page 22: Taking Depth And Current Measurements

    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 vScan on the ground making sure it is vertical and across the line.

  • Page 23: Metal Locate Mode (Vscanm Cover Detector)

    Locating Metal Locate Mode (vScanM Cover Detector) The metal locate mode is used to detect buried manhole covers. For this feature, be sure to order vScanM. The cover locator has been designed to respond to most metal covers. 4.6.1 Locating a Buried Cover Before locating a buried cover it is necessary to perform a simple set up procedure.

  • Page 24: Locating Non-Metallic Pipes Or Ducts

    Switch on the Sonde by connecting the battery. Connect it to the pushrod and place it in the start of the pipe run. Switch on the vScan and select Sonde mode using the mode paddle. The Sonde icon will now be visible on the screen.
  • Page 25 Now sweep left and right over the Sonde to obtain a second peak. Note that there are no ghost signals when sweeping left to right over the Sonde. Finally check that the vScan is in line with the Sonde by rotating it on its axis to obtain a peak signal. The vScan is now over the Sonde and in line with it.

  • Page 26: Advanced Locating Techniques

    This is an induction method technique and is used to quickly check an area for any metallic services. Method: Select the area to be checked. One person holds the transmitter and the other holds the vScan receiver. Attach the carry strap to the transmitter. This is important as it makes carrying the transmitter more comfortable and allows the transmitter to be held close to the ground ensuring maximum coupling to the services below.

  • Page 27: Nulling Out A Signal (Induction Mode)

    Locating Position the vScan receiver approximately 10m from the transmitter and with the flat of the blade pointing directly at the transmitter. Switch it on and adjust the sensitivity so that approximately 20% reading is observed. Walk slowly around the transmitter watching for an increase in signal level. At an increase, pinpoint the source of the signal and mark the ground at the maximum point.

  • Page 28: Capacitive Coupling

    Locating Now position the vScan receiver exactly over the unwanted signal. The person at the transmitter end can now hold the transmitter vertically over the position of the unwanted signal. Move the transmitter side to side across the line of the unwanted service whilst asking the person at the receiver end to indicate when the signal is “nulled out”.

  • Page 29: Self-Test/Calibration Check

    4.9.1 The vScan Receiver The vScan has been designed to be a robust and stable avoidance tool. However, as with all safety equipment it is advisable to check the functionality of the equipment. As the receiver is the signal processing part of the kit, Vivax-Metrotech has designed into the equipment a calibration and functionality check.

  • Page 30: Vscan Transmitter Check

    Note that this test does not test the metal cover detector of the vScanM. To check this, simply check that the unit detects a 6” (150mm) metal cover at a range exceeding 6” (150mm). 4.9.2 vScan Transmitter Check As the transmitter is not a measuring device, it is not necessary to perform calibration checks on the equipment. However, it is advisable to perform this quick and easy functionality check.

    Note that there will be no satellite access within buildings. The vScan has quick start up circuitry for the GPS. It works by holding power to the GPS circuitry for a period of 30 minutes (or as set by MyvScan) after switch off. The circuitry is activated when the unit is put into the “Standby” mode. If the unit is switched back on, from the “Standby”...

    The Bluetooth feature enables the vScan to communicate with external devices, such as high accuracy GPS and data logging devices, via a radio link. Before data can be exchanged with the external device, the two units need to be electronically paired. The vScan screen shows the status of the Bluetooth via the Bluetooth icon: •...
