Who Can Use This Equipment
• This equipment must only be used by people suitably trained in the use of pipe and
cable locators.
Work-site Safety
• Use your company’s or other applicable safety codes and rules when using this
equipment.
• Unless having the required authorization, license and appropriate training – do not
make connections to any pipe, cable or conductor.
• The equipment should not come in contact with corrosive or hazardous chemicals,
gases or dust.
• Do not directly connect this equipment to cables or pipes with a potential di󰀨erence
to ground greater than 25V AC.
Equipment Safety
• Do not open the enclosures (housings) of either the transmitter or receiver.
• Place the ground stake rmly in the ground before connecting the cable from the
transmitter.
• Do not hold any uninsulated portion of the connection leads & clips when the
transmitter is switched on.
Batteries and Environmental Safety
Vivax-Metrotech products use four types of batteries:
• Alkaline batteries
• Ni-MH (Nickel-Metal Hydride) batteries – rechargeable
• Lithium-Ion batteries – rechargeable
• Lithium-Metal batteries – (small non-rechargeable button cells for “clock”
applications)
1. Alkaline Batteries (Non-Rechargeable)
• When replacing the alkaline batteries – use only the size and type specied – do
not mix battery types (rechargeable and alkaline.
• Do not mix partially discharged and fully charged cells in the same battery pack –
do not mix old with new.
• Never attempt to charge alkaline batteries.
2. Nickel-Metal Hydride Batteries (Rechargeable)
• When using rechargeable batteries, use only the correct charging device supplied
or specied by the manufacturer. The battery pack or charger will contain circuitry
to manage the charging process. Other chargers (even if they have the same
connector, polarity, voltage & current rating will not have the same control circuitry
and can cause damage to the product, overheating, and in extreme cases, re or
harm to the individual.
• Do not assume that if the plug ts, it is the correct charger – a charger with the
correct part number must be used – just because it is a Vivax-Metrotech charger
and the plug ts does not mean it is the correct charger.
• Before using for the rst time, charge rechargeable batteries for six hours. If the
rechargeable batteries do not last as long as anticipated – discharge fully and then
charge for six hours.
• Care should be taken when charging batteries – Never repeatedly recharge
batteries (or turn the power o󰀨 & on) without using the instrument. If used with an
inverter in a vehicle, charge the product, unplug the charger, and not charge again
until the rechargeable batteries have been used for at least ten minutes. Failure to
do this could result in the overcharging of the battery, which will shorten the battery's
life and could, in some circumstances, cause overheating or re.
• If the product becomes hot during the charging process, immediately unplug
the charger and use the rechargeable batteries for at least ten minutes before
recharging. If this reoccurs the next time the unit is charged – return immediately to
Vivax-Metrotech for repair.
• Do not charge batteries for prolonged periods without using the locator for at least
ten minutes. Charging for prolonged periods could overcharge the battery, reduce
battery life, damage the locator and re in extreme circumstances.
3. Lithium-Ion Batteries (Rechargeable)
• Lithium-Ion Batteries – some products use Lithium-Ion batteries – the requirements
for marking and transportation are still developing. Please contact Vivax-Metrotech
before shipping products containing Lithium-Ion batteries or Lithium-Ion battery
packs on their own for any “special instructions.”
4. Lithium-Metal Batteries (Non-Rechargeable)
• Commonly known as “button cells,” these are small – non-rechargeable batteries
used to power internal “clocks” within some units (similar to computers). Generally,
they have a life of three to ve years.
• Under no circumstances should any attempt be made to charge these batteries.
• Dispose of according to your company’s work practice/environmental standards, the
prevailing laws, or recognized best practice. Always dispose of batteries responsibly.
5. General Rules regarding Disposal of Batteries
• Never disassemble a battery or battery pack.
• Never dispose of in a re or water.
• Dispose of batteries following your company’s work practice/environmental
standards, the prevailing laws, or recognized best practice. Always dispose of
batteries responsibly.
6. Transportation of Lithium-Ion and Lithium-Metal Batteries
• The Lithium-Ion and Lithium-Metal batteries used in Vivax-Metrotech products meet
the required safety standards and include the designated protection circuitry.
• Recent regulation changes require that when batteries with Lithium-Ion and Lithium-
Metal batteries are transported, the packaging must include specified warning
labels.
• Please contact Vivax-Metrotech Customer Service (USA 1-800-446-3392,
International [phone] (USA Pacic Time Zone)) for more details.
• Regulations have also changed regarding the shipping of spare battery packs (battery
packs that are not inside a product). There are limitations on the package's weight,
and the packaging must be marked with the appropriate warning labels.
• Please contact Vivax-Metrotech Customer Service (USA 1-800-446-3392,
International [phone] (USA Pacic Time Zone)) for more details.
• Vivax-Metrotech vLoc Series 3 products using Lithium-Ion battery are classied as
“not restricted.” They can be shipped normally by road/rail/sea & air (passenger &
freight aircraft) without restrictions.
IMPORTANT
Remember – Batteries contain dangerous chemicals –
They can be a󰀨ected by many things such as water ingress
or heat – In some circumstances, they can explode. They
also can cause electric shocks!
Care of Equipment
• Use equipment only as directed in this User Handbook.
• Do not immerse any part of this equipment in the water.
• Store in a dry place.
• Keep equipment in the case provided when not in use.
• If left for a prolonged period – remove alkaline batteries.
• Keep unit clean and free of dust and dirt.
• Protect against excessive heat.
Care when Interpreting the Information provided by the Locator
• Like all locators – this instrument is locating and providing depth and current
readings based on electromagnetic signals that radiate from the buried cable or
pipe. In most cases, these signals will enable the locator to pinpoint both position
depth and current correctly.
• Beware – in some cases, other factors will distort electromagnetic elds radiating
from cable or pipe is located, resulting in incorrect information.
• Always locate responsibly and use information learned during your training to
interpret the information provided by the locator.
• Do not provide information regarding cable or pipe depth to anyone unless
authorized to do so by your company.
• Remember that depth measurements are to the center of the electromagnetic eld or
pipe – In the case of pipes, this may be signicantly deeper than the top of the pipe.

2 Introduction
2. Introduction
2.1 About this Manual
This handbook assumes some understanding of Cathodic Protection techniques.
This manual covers the vLoc3-DM Receiver, 25-watt transmitter and 150-watt transmitter.
2.2 Overview of vLoc3-DM System
The vLoc3-DM (Defect Mapper) has been designed to:
• Identify the position of coating defects
• Identify shorts to other structures
• Help categorize the faults
• Help plan and prioritize remedial work
• Operate as a long line pipeline locator
The vLoc3-DM uses the latest locating and signal processing techniques to plot the current gradient of an industry-standard low
frequency (3Hz or 4Hz) proling current. The current is typically applied at CP (Cathodic Protection) stations, so the pipeline's
disruption can be minimized.
The Loc-150Tx (150-watt) transmitter applies a signal current to the anode bed. The pipeline returns the signal via coating faults
back to the transmitter. The transmitter is designed to be powered from CP stations, AC or external batteries. Note that the
Transmitter Link option is not available for the Loc-150Tx Transmitter.
The Loc3-25Tx 25-watt transmitter is a portable version of the 150-watt transmitter. A custom rechargeable Li-ion battery tray
powers the 25-watt transmitter.
The vLoc3-DM receiver is a non-intrusive measuring device to take measurements along a pipeline. These measurement
results are displayed on the screen of the receiver. The measurements and data are logged into the receiver for downloading to
spreadsheets or dedicated analysis programs. There is no need to carry extra logging and display devices.
An internal +/- 3m accuracy GPS antenna is included with the system. Alternatively, a Bluetooth-enabled GPS device can be
linked to the vLoc3-DM receiver via a Bluetooth radio link. The GPS enables the user to generate real-time current gradient
graphs and guides them back to the point of interest by highlighting the user's position on the graph. This feature is called the
"walk back" feature. The system can also be integrated with other high-accuracy GPS systems and software packages.
Storing the results also has the benet of facilitating the technique of comparative testing. Comparing the results from previous
surveys of the same length of the pipe allows the Cathodic Protection engineer to establish coating deterioration trends.
The A-frame fault-nding accessory is used to locate the position of a fault accurately. An arrow points the user to the fault's
position while quickly and e󰀩ciently graphing the fault signal's characteristic shape and magnitude on the receiver's display.
The A-frame is also used to undertake full ACVG surveys along a pipeline route. Results are stored with GPS data and real-time
graphs generated on the vLoc3-DM screen.
Setting the vLoc3-DM to simultaneous mode allows the user to take ACVG and current proles during just one simultaneous
survey of the pipeline.

™
Page 4 of 65
2 Introduction
2.3 Planning a Survey
Surveys will vary greatly depending on the type of terrain, accessibility, condition of the pipeline, type of pipeline and coating
type.
The rst step of undertaking any survey should be to obtain information about the pipeline stretch to be surveyed. More work
at this stage may well save time and e󰀨ort later. Obtaining maps showing route information, CP stations, sacricial anodes and
cross bonding points will signicantly help.
The transmitter should be capable of transmitting from one CP station to another, so although not necessary, plan to have
the previous and after CP stations disconnected from the pipeline's stretch to be surveyed. Remember that the pipeline is not
protected while the survey is being undertaken so CP stations' unnecessary downtime should be avoided.
Choose the survey interval to match the condition of the pipeline. In areas where the coating is inferior a survey interval of as
little as 10m may be desirable. However, if the coating is in excellent condition and the distance between CP stations is many
km, it may be better to choose a survey interval of as much as 200m. Taking measurements at large intervals will enable the
surveyor to assess the pipeline's condition quickly and subsequently identify areas requiring further inspection at closer survey
intervals or detailed analyses using the A-frame Fault Finder accessory.

3.2 DM Low-Frequency Sensor Foot
The device at the bottom of the locator tube is the DM low-frequency sensor foot. This device is used to detect the low-
frequency component (frequencies between 3Hz and 8Hz). These are the vLoc3-DM current mapping frequencies. When the
low-frequency mapping is not required, for instance, if the equipment is being used for pipeline locating but not defect mapping,
the low=frequency sensor can be removed.
Removing the DM sensor foot will reduce the locator's weight and change how the logging is done. The logged frequency will
then be the locate frequency selected and graphing will also use this frequency.
3.2.1 Removing the DM Low-frequency Sensor foot
Rotate the retaining screw on the bottom of the receiver stem counter-clockwise for ¼ turn.
Grasp the low-frequency sensor and rotate it counterclockwise until it releases.
Now t the blanking plate supplied by following the above instructions in reverse order.
IMPORTANT
Always install the blanking plate when the low-frequency sensor foot is not attached. There are critical
contacts within the antenna tube that require protection. Failure to do so may void the warranty.
When setting the retaining screw on the side of the antenna tube, hand tighten only.
3.3 Charging the Receiver Batteries
The vLoc3-DM can be used with either alkaline batteries or an interchangeable rechargeable battery pack.
The central illuminated section within the battery icon indicates the amount of charge remaining.
Blue center indicates Alkaline batteries.
Green center indicates rechargeable batteries.
When batteries are low the remaining charge section becomes red and will ash.
Just before the shutdown the below symbol will be shown:

3 vLoc3-DM Receiver Functions and Operations
Rechargeable batteries are supplied with a mains charger that is specic to the batteries. Avoid using other manufacturers’
chargers as these may damage the battery pack and result in overheating.
To charge the rechargeable batteries, rst make sure the pack is inserted in the receiver battery compartment. Charging is done
with the battery inside the receiver.
Connect the charger to the charging socket of the receiver. Connect the charger to the mains and switch it on. The LED indicator
on the charger will illuminate red until the batteries are fully charged, at which time the LED will change to green.
WARNING
Rechargeable batteries are supplied with a mains or 12V DC charger. These are specific to the
batteries. Only use the charger that is appropriate for the batteries in the product. If in doubt call the
Vivax-Metrotech customer service department at [phone]. Failure to use the appropriate
charger could damage the battery pack, locator and in extreme cases cause a re.
Avoid charging the unit in extreme temperature conditions, i.e., below 0ºC and above 45ºC
Although Vivax-Metrotech batteries include all the required safety-related features, immediately
discontinue the charger and battery pack's use if the battery pack becomes excessively warm. Return
both to where they were purchased for investigation.
Always ensure batteries have at least a partial charge if storing for long periods without use.
Dispose of all batteries following your company procedures and or Federal/State and local
regulations.
Never dismantle the battery pack, put them in a re, or get them wet.

3 vLoc3-DM Receiver Functions and Operations
3.5 The vLoc3 Series User Menu
The user-congurable vLoc3 series receivers can be customized to suit the user’s preferences. The receivers have several
features that can be switched on and o󰀨 through the user menu.
This section covering the user menu is split into four subsections;
Setup – Covers the settings that are usually chosen and not often changed. Most of these settings apply to the locator's physical
attributes such as language, sound, and measure units.
Operational – Covers the locate screens and locate perspective.
Features – Are optional modes and physical add-ons such as Bluetooth, Marker Locator Adapter, and other options that may
have been ordered.
Informational – Covers the receiver’s conguration, rmware version, and regulatory information.
It is recommended that the Setup section be done rst. It will be easier to nish the receiver's setup if it is done in the native
language.
To enter the user menu, press and hold the “i” key, release the key when in the menu.
Note that where you see this symbol , pressing the enter button gives access to the sub-menu associated with this button.
To exit the menu or sub-menu, press the “i” button.
Where the icon is not shown, the enter button is used to scroll through the options of that feature.
Use the “+” and “-” buttons to scroll up and down through the menu.
