3.5 Dynamic overload
protection
TM
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
locator’s digital signal processor. DOP is an
integrated feature of all 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
from becoming overloaded. If the
becomes overloaded, users will be alerted by the mode
flashing and both the depth and current measurements
will be disabled.
3.6
TruDepth™ measurement
All locators use TruDepth to estimate depth
automatically when a good reading is established.
NOTE: TruDepth only indicates a locate depth when the
locator is correctly oriented above the target line, cable
or sonde, or in close proximity of the RF marker.
To help you orientate the locator correctly, you can use
the locator’s compass feature on the display – feature
not available in marker mode.
Depth readings are displayed according to your
preferred units of measurement.
For more information on measuring depth, please refer
to Section 6.
3.7 Strike Alert
™
Strike Alert detects the possible presence of shallow
power signals and warns the operator with a series of
flashing asterisks on the display and an audible alarm,
characterized by a rapid warbling sound.
locators are shipped with Strike Alert enabled
by default, which can be disabled by accessing the
StrikeAlert menu and setting StrikeAlert to OFF.
StrikeAlert will activate in Power and Passive mode
only.
Strike Alert can also be permanently disabled using the
RD Manager PC software. Refer to its operation manual
for further information.
WARNING! Muting audio on the locator will disable
Strike Alert Audio alarm.
