3.3 Locating Mode (Response)
The vLocPro receiver has four antennas, and these can be toggled through different congurations
(modes) to provide different responses to the signals radiating from the buried pipes and cables.
The modes are:
The vLocPro 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:
Compass Line
Direction Indicator
Compass Line
Direction Indicator
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 identiable “Peak”. In
3.3.2 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.

3.3.1 Peak Response Mode
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.
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.

3.3.3 Null Mode
3.3.4 Sonde 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.
Pushbutton Icon
Sonde mode uses the antennas in a “Peak” conguration. 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.
Pushbutton
Compass Line
Direction Indicator
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.

The vLocPro 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 7.1.3.
3.4 Display
These responses are shown on the display as
● Moving Bar graph
● Numeric value & db value
● Directional arrows (with ‘Null’ response)
● A range of different display modes will be available in 2009
3.5 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 two seconds to
enter setup menu. The setup display defaults to volume. Use the “Mode” 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 signicant amount of power, using lower volume can
make the battery life of the receiver last longer.

3.6 Sensitivity Control
The vLocPro 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 dened 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 specic 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” mode
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.
Up & down 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 60% deection (i.e. if the bar graph
goes towards the minimum – press the “+” pushbutton, to the
maximum press the “-” pushbutton)
Holding down or repeated pushing of the “+” or “-” pushbuttons increments/decrements the gain.

3.8 Information Pushbutton (Depth & Current)
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 90oto the ground.
3.9 Setup Menu

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 receiver has two battery packs.
● External alkaline battery pack. Icon A indicates the status of the external battery pack.
● Internal rechargeable batteries. Icon B indicates the status of the internal battery pack.
The unit will operate from the internal batteries until they have no charges left. The unit will then
automatically switch over to the external alkaline batteries when this occurs.
The receiver has an internal rechargeable battery – this will provide the power to the unit unless
you connect an alkaline battery pack. This allows the user to benefit from using rechargeable
batteries, but enables the use of alkaline batteries if for any reason the rechargeable battery lacks
charge.
