4.6 Dynamic Overload
Protectio
n™
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 lo
cator’s digital signal
processor. DOP is an integrated feature of all RD8100
locators. No action is required by the user.
NOTE: 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.
