Dynatel 2250 Advanced Cable Locator
Pinpoint exact cable path and depth
quickly and easily with this lightweight,
easy-to-handle unit
Dynatel PDF: Charts and Specifications
The 3M™ Dynatel™ 2250 Advanced Cable Locator is a
micro-processor-based system that incorporates advanced
digital signal processing techniques to quickly and
efficiently trace the path of underground cables, both copper
and fiber optic (with metallic trace wire). Lightweight,
compact and well-balanced, the locator accurately:
• Locates cable path
• Measures cable or sonde depth with the push of a button
• Measures signal current in the cable
• Identifies cable and cable pairs
• Identifies cable pairs through wet sections
• Locates energized power cable with direct readout of
cable depth
The 2250 cable locator provides accurate cable or sonde
depth measurements, giving a digital readout in inches, feet
and inches, or centimeters (user-selectable).
Additionally, when used in conjunction with the 3M
Dynatel 2205/2206 EMS Marker Locating Accessory, the
locator can:
• Pinpoint the exact location of buried EMS markers
• Trace a cable path while simultaneously finding buried
markers along the way
Four modes of operation for accurate
locates, even in congested areas
For cable path locating, the Dynatel 2250 receiver uses one
of four user-selected locating modes – dual peak, dual null,
differential or special peak (which increases the sensitivity
of the receiver for tracing over longer distances). The mode
is selected depending on which is most effective under the
locating conditions.
The receiver includes four volume settings, including a
special “expander” function that makes peaks and nulls
more pronounced. The expander feature enhances the
amplitude difference between two conductors carrying the
same signal, making the unit extremely accurate, even in
congested areas. A headphone jack is also included.
A simple, easy-to-use system
The Dynatel 2250 Advanced Cable Locator is easy to
operate and requires very little training. Digital liquid
crystal display (LCD) readout and push-button operation
make the unit easy to understand, for more precise locates.
A “memory” feature remembers operator set-up from
previous use.
The system consists of two basic components:
• Transmitter with built-in ohmmeter, which also senses and
measures the presence of foreign voltage, and tests the
continuity of the circuit.
• One-piece hand-held receiver with bar graph that indicates
received signal and proximity to the cable.
The 2250 cable locator uses four active trace
frequencies — 577 Hz, 8 kHz, 33 kHz and 200 kHz —
which can be used individually or simultaneously to
compensate for varying field conditions. The receiver
incorporates passive power and auxiliary frequencies that
do not require the use of the transmitter.
Both the receiver and the transmitter feature a self-test
routine which is executed each time the unit is turned on.
A power-up battery test indicates battery level.
Both components are constructed of heavy-duty
materials designed to withstand typical field use.
