3.6.3 Selecting frequencies
It is important to select the correct or appropriate frequency
for your particular application. For more information see
Section 6 or refer to the "ABC & XYZ of locating buried
pipes and cables", which is available as a free download
from www.radiodetection.com.
To select a frequency on the locator:
1.
Switch the unit on by pressing the
have not already done so.
2.
Press the
key to cycle through available
frequencies.
3.
Alternatively, hold down the key and press the up
or down arrows to cycle up or down the range of
frequencies.
If using an active frequency you must also set your
transmitter to output the matching frequency. You can
change your transmitter's output frequency manually using
your transmitter's keypad or automatically using iLOC
(iLOC enabled locators and transmitters only).
To manually select a transmitter output
frequency:
1.
Switch the unit on by pressing the
have not already done so.
2.
Press the
key to cycle through available
frequencies.
NOTE: Some frequencies require that you connect
an accessory, for example an A-Frame, before the
frequency is available.
3.7 TruDepth
™
The RD7000+ uses TruDepth to automatically estimate
depth when a good reading is established.
NOTE: TruDepth only indicates a locate depth when the
locator is correctly oriented directly above the detected
pipe or cable.
To help you orient the locator correctly, you can use the
locator's compass on the LCD screen
Depth readings are displayed according to your preferred
units of measurement as follows:
•
Less than 1 meter: depth is displayed in centimeters.
•
Greater than 1 meter: depth is displayed in meters.
•
Less than 3 feet: depth is displayed in inches.
•
Greater than 3 feet: depth is displayed in feet.

For more information on measuring depth, please refer
to Section 5.
3.8 SideStepauto
SideStepauto allows the transmitter to calculate the
optimum frequency based on ground impedance.
The transmitter uses this information to optimize the
active frequency. SideStepauto helps to improve locate
accuracy by determining the best signal. SideStepauto
can also help to prolong battery life.
NOTE: SideStepauto will only work in direct connection
mode. Inductive frequencies are not supported.

3.9 Dynamic Overload Protection
The RD7000+ range features Dynamic Overload
Protection (DOP). DOP allows you to locate accurately
in areas with high levels of electromagnetic interference,
such as sub-stations and beneath high-voltage
transmission lines. DOP works by disregarding signal
spikes that would otherwise overwhelm the RD7000+'s
digital signal processor. DOP is an integrated feature of
the RD7000+ range. No action is required by the user to
enable it.
