“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
