4.6 Dynamic Overload
Protection™
Dynamic Overload Protection™ (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 RD8100 locator’s digital signal
processor. DOP is an integrated feature of all RD8100
locators. No action is required by the user.
4.7 Overload warning
In cases of high levels of electromagnetic interference,
the DOP will not be able to prevent the RD8100 from
becoming overloaded. If the RD8100 becomes
overloaded, users will be alerted by a flashing mode
icon. Both the depth and current measurements will be
disabled in the event of an overload.
4.8 TruDepth™ measurement
All RD81 00 locators use TruDepth™ to measure depth
automatically when a good quality reading can be
assured.
NOTE: TruDepth only indicates a locate depth when
The locator is correctly oriented above the target
line, cable or sonde.
The local signal conditions are assessed as be
good enough to ensure an accurate reading
To help you orientate the locator correctly, you can use
the locator’s compass feature on the screen
Depth readings are displayed according to your
preferred units of measurement.
For more information on measuring depth, refer to
Section 6.
