General Safety & Care Information
1.1 Who Can Use This Equipment
This equipment must only be used by people suitably trained in the use of pipe and cable locators.
1.2 Work-site Safety
Use your companies, or other applicable safety code 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, or gases, dust.
Do NOT directly connect this equipment to cables or pipes that have a potential difference to ground of
greater than 35V AC.
1.3 Equipment Safety
Do NOT open the enclosures (housings) of either the transmitter or receiver.
Place the ground stake firmly 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.
1.4 Batteries and Environmental Safety
Vivax-Metrotech products use four types of batteries:
Alkaline batteries – non rechargeable
Ni-MH (Nickel Metal Hydride) batteries – rechargeable
Lithium-ion batteries – rechargeable
Lithium metal batteries – (small non rechargeable button cells for “clock” applications)
1.4.1 Alkaline Batteries (Non Rechargeable)
When replacing the alkaline batteries – use only the size and type specified – 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.
1.4.2 Nickel Metal Hydride Batteries (Rechargeable)
When using rechargeable batteries, use only the correct charging device supplied or specified by the
manufacturer. The battery pack or the battery 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
fire or harm to the individual.
Do NOT assume that if the plug fits 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 fits does NOT mean it is the
correct charger.
Before using for the first time, charge rechargeable batteries for 6 hours. If at any time the rechargeable
batteries do NOT last as long as anticipated – discharge fully and then charge for 6 hours.
Care should be taken when charging batteries – NEVER repeatedly recharge batteries (or turn power off
& on) without using the instrument. If used with an inverter in a vehicle – charge the product then unplug
the charger and do 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 life of the
battery, and could in some circumstances cause overheating or fire.
If ever the product becomes hot during the charging process IMMEDIATELY unplug the charger and use

1.6 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 fields radiating from cable or pipe
being 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 depth of cable or pipe to anyone unless authorized to do so by
your company.
REMEMBER that depth measurements are to the center of the electromagnetic field or pipe – In the case
of pipes this may be significantly deeper than the top of the pipe.

3.2 Charging the Receiver Batteries
The vLoc-5000 can be used with either alkaline batteries or it can be supplied with an interchangeable
rechargeable battery pack.
When alkaline battery is used, Icon A will appear on the screen. When the rechargeable battery pack is used,
Icon B will be displayed.
In both cases, the number of bars illuminated within the battery icon indicates the amount of charge
remaining.
Rechargeable batteries are supplied with a mains charger. This is specific to the batteries, avoid the use of
other manufacturers’ chargers as these may damage the battery pack and may result in overheating of the
battery pack.
To charge the rechargeable batteries, first make sure the pack is inserted in the receiver battery compartment
as charging is done inside the receiver. Insitu.
Connect the charger to the charging socket of the receiver. Connect charger to the mains and switch 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 Vivax-Metrotech Customer Service. Failure to use
the appropriate charger could result in damage to the battery pack, locator and
in extreme cases cause fire.
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 always immediately discontinue use of the charger and battery pack 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 in accordance with your company procedures and
Federal/State and local regulations.
Never dismantle batteries, put them in fire, or get wet.

The vLoc-5000 is a Precision Location System designed to meet the needs of Utility Companies and their
contractors. The following describes the features and use of the receiver.
3.5 Distance Sensitive Left/Right Guidance™ Display
The Left/Right display is tremendously useful in refining the precise location of the target line. The vertical
green bar represents the underground utility and when shown on the left of centerline it indicates the target is
also to the left.
Distance Sensitive Left/Right Guidance
Using Vivax-Metrotech’s Distance Sensitive Left/Right Guidance feature, the deflection distance of the
vertical black bar away from the center of the display is proportional to the distance off center from the
underground line. Although this is strictly true only when the field is free of distortion, the Left/Right display
still plays an important role in sorting out what is going on in the underground utility environment.

Page 10 of 57
Distance Sensitive Left/Right Guidance
Often the receiver is used in a left to right sweeping motion over the centerline of the tracked utility. When the
action in the Left/Right display is non-symmetric, this can be a warning of the presence of distortion in the
field. Care should be taken to determine the effect of other cables in the locate zone that might be creating
distortion by carrying bleed over and return currents.
Distance Sensitive Left/Right Guidance
3.6 Locating Mode (Response)
The vLoc-5000 receiver has four antennas, and these can be toggled through different configurations
(modes) to provide different responses to the signals radiating from the buried pipes and cables. The modes
are:
3.5.1 Peak Response Mode
This uses the two horizontal antennas and provides a “Peak” or maximum
signal response over the center of the radiated signal from the buried line.
The compass line direction indicator shows the direction of the cable
(available in Active modes). The color of the compass changed from clear
to blue when the receiver is in line with the buried line.
This is the most accurate of the locating modes as both antennas are
used to provide a clearly identifiable “Peak”. In the “Peak” mode, a “Peak”
signal indicator helps to clarify the position of the “Peak”. This shows the
last “Peak” located for a few seconds, enabling the user to return to that
position quickly.

Page 11 of 57
3.5.2 Broad Peak Mode
This uses a single horizontal antenna and provides a “Peak” or maximum
signal response over the center of the radiated signal from the buried line.
The compass line direction indicator shows the direction of the cable
(available in Active modes). The color of the compass changed from clear
to blue when the receiver is in line with the buried line.
This is less accurate than the twin horizontal antenna “Peak” mode – but
is useful if the buried line is particularly deep. For pinpointing the line, the
“Peak” mode should be used.
3.5.3 Null Mode
This uses vertical antennas and provides a minimum or “Null” response
over the center of the radiated signal from the buried line. The compass
line direction indicator shows the direction of the cable (available in Active
modes). The color of the compass changed from clear to blue when the
receiver is in line with the buried line.
Some users prefer the null response; it works well in uncongested areas,
but is more prone to inaccuracies due to distortion of the radiated signal
in congested areas.
Left/right indication arrows are also displayed when in “Null” mode. The
arrows indicate the direction to move the receiver to locate the position of
the buried line.
3.5.4 Sonde Mode
Sonde mode uses the antennas in a “Peak” configuration. An ICON on
the display indicates if the receiver is in Sonde mode.
A Sonde is a small transmitting coil that is powered by its own internal
battery, or by an external transmitter.
Due to its construction, a Sonde gives a different “Peak” pattern - when
locating along the direction of the Sonde - instead of the usual single
“Peak”, the Sonde provides three distinct peaks - a small “Peak” - a large

“Peak” - a small “Peak”. The Sonde is located under the center of the
large “Peak” when located across the direction of the Sonde and it gives
the conventional peak response. Note that the Compass Line Indicator
points across the line of the Sonde when directly over it and the color of
the compass change from clear to blue.
The vLoc-5000 receiver must be used in a different orientation when
locating a Sonde – due to the way the signal from the Sonde radiates.
With the front of the receiver pointing across suspected direction of the
Sonde – pinpoint forward and backward (across the Sonde) and then
move along the line of the Sonde until the maximum peak is located (in
other words rotate the receiver 90 degrees from the orientation normally
used when locating pipes and cables).
A Sonde is typically used for locating non metallic pipes or ducts, and the
camera end of a sewer inspection camera. Low frequency versions (512
Hz/640 Hz) can transmit through some metallic pipes such as cast iron
pipes – which are why they are frequently used with sewer inspection
cameras.
For using the compass feature to locate Sondes, please refer to 9.1.3.
3.7 Audio
The visual display is also accompanied by an audio response. The output level (volume) of this response is
set by entering the “Setup Menu”. Press and hold “i” pushbutton for 2seconds to enter setup menu. The setup
display defaults to volume. Use the “M” pushbutton to toggle through the available options (Off - Low - Med -
High). Press the “i” pushbutton again to exit the setup menu. As the loudspeaker uses a significant amount of
power, using lower volume can make the battery life of the receiver last longer.
3.8 Sensitivity Control
In manual modes, “+” and “-” pushbuttons are provided to increase or reduce the sensitivity of the receiver. If
the bar graph moves towards the minimum or maximum a single touch of the opposite pushbutton returns it
to approximately 50% deflection. Holding down or repeated pushing of the “+” or “-” pushbuttons
increments/decrements the gain.
3.9 Frequency Selection
The vLoc-5000 receiver is capable of locating a large number of frequencies or frequency combinations. A list
of these frequencies can be accessed using the setup menu. Most of these frequencies listed – you will
never use – the setup menu allows you to select the frequencies you wish to use regularly. The frequency

select pushbutton on the main receiver pad is used to toggle through the frequencies defined using the setup
menu. The operating frequency will be shown at the lower right side of the display. You can change this
selection at any time using the setup menu.
The initial frequencies set at the time the unit is supplied are “Power”, “Radio” and the frequencies used by
the transmitter purchased. See the transmitter section for suggestions of which frequency is best suited to
specific applications.
To select the frequencies you wish to use regularly – enter the setup menu
by pressing and holding the “i” pushbutton for 2 seconds. Use the “+” and
“-” to select the word “Frequency” – then press the “M” pushbutton to
display the list of available frequencies.
The “+” and “-” pushbuttons are used to navigate the list of frequencies. To
add a frequency to the “Frequently used list” press the “M” pushbutton and
a dot will appear in the circle alongside the frequency. To deselect a
frequency press the “M” pushbutton and the dot will disappear. Once your selection is completed press “i”
pushbutton once to return to the setup menu, and again to exit the setup menu.
3.10 Information Pushbutton (Depth & Current)
Pressing the “i” (information) pushbutton will display the depth to the center of the radiated signal and a
measurement of the current (press the pushbutton briefly – remember if you press and hold – you enter the
setup menu. If you do enter the setup menu – press the “i” pushbutton again to return to the locating screen –
then try again).
The display shown above shows Long/Lat positional informaiton. This is only displayed when the equipment
is paired with a valid GPS system.
IMPORTANT
When locating a cable or pipe (“Line”) – the instrument should be in “Peak”
mode and the depth and current measurements should only be taken with the
bottom of the receiver standing on the ground and directly in line with the
target line.
IMPORTANT
When locating a Sonde – set the mode to Sonde - then the instrument will
automatically be in “Peak” configuration. Depth measurements should only be
taken with the bottom of the receiver standing on the ground and at ninety
degrees to the Sonde.
The accuracy of depth and current readings depends on the quality of the radiated signal being located. If the
signal is symmetrical, the depth reading will be accurate to within 5% of the actual depth. If the signal is
distorted, depth readings will be less accurate. When taking depth measurement, always hold the receiver at
900to the ground.

4 Data Logging
Page 15 of 57
Data Logging
The vLoc-5000 has an internal memory that can be used to store location data. It can store in excess of 1000
records.
To store a record first locate a point of interest. Hold the vLoc stationary over the target and press the “i”
pushbutton. When in the depth and current screen, press the “+” pushbutton to save the data. The “Log”
number indicates the number of records stored.
If the GPS function is enabled the GPS coordinates will also be displayed and attached to any saved file. For
more information on Data logging and GPS see section 5.2.5.4.
4.1 Bluetooth
As an optional extra the vLoc-5000 receiver can be fitted with a Bluetooth communications accessory. The
Bluetooth option can be retrofitted and can be ordered at a later date if preferred.
4.1.1 Fitting the Bluetooth Module
1. Ensure the unit is switched off.
2. Use a small cross head screw driver to remove the two screws retaining the Bluetooth cover. This is
found at the back of the handle near the battery compartment.
3. Remove the cover by sliding it away from the handle.
4. Take the Bluetooth module and carefully slide it into the position the cover was occupying.
5. Replace the two cross head screws.
6. Switch on the unit and after a few seconds a grey, Bluetooth icon should appear showing that the module
is fitted.
7. If a red line is shown through the icon, this indicates that the Bluetooth module is not enabled. Bluetooth
enable is located in the user menu which is accessed using a long press of the “i” button.
8. The Bluetooth can communicate with external devices that are also Bluetooth enabled. There are many
Bluetooth enabled GPS devices but Vivax-Metrotech offer the Holux GPS as a suitable solution for those
requiring mapping to accuracies better than 5m. For those requiring accuracies better than this, for
instance submeter accuracy, the customer should contact a GPS supplier of their choice. However, as a
recommendation, one such device that delivers submeter accuracy is the Trimble ProXT.
