3M Dynatel 2250-U3P3 Advanced Cable Pipe Locator

 3M Dynatel 2250 Advanced Cable Locator

Pinpoint exact cable path and depth quickly and easily with this lightweight, easy-to-handle unit
The 3Mﾙ Dynatelﾙ Advanced Cable Locator 2250 is a microprocessor-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 using toning function
• 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ﾙ Dynatelﾙ EMS Marker Locating Accessory 2205/2206, 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 2250 receiver uses one of four userselected locating modes ﾖ 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 ﾓexpanderﾔ 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 3Mﾙ Dynatelﾙ Advanced Cable Locator 2250 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 ﾓmemoryﾔ 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 ﾗ 577 Hz, 8 kHz, 33 kHz and 200 kHz ﾗ 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.

Transmitter Features:

• Four operator-selectable frequencies
  • Optimizes unit performance in varying conditions
• Simultaneous signals
  • Enables receiver to verify cable location
• Built-in ohmmeter with voltage sensing/measuring capability
  • Displays earth fault resistance; confirms far-end grounds and shield continuity
• Three signal application methods (direct connect, coupler, induction)
  • Flexibility under varying plant conditions
• Auto load (impedance) matching
  • Automatic adjustment of output voltage to maximize signal
• High and normal output level
  • High output level for extreme distance locates and other varying cable conditions
• Displays output signal current in trace mode
  • Assists in proper frequency selection and setup
• Audible indication of hazardous voltage in ohms mode
  • Warns operator of potentially dangerous situation
• Can connect to energized power cables up to 240 Vac
  • Prevents inadvertent damage to unit; operates while attached to live circuits

Receiver Features:

• Peak and null modes
  • Verify cable location
• Differential mode
  • Indicates direction to cable
• Push-button digital depth readout (of cable or sonde) in inches, feet and inches, or centimeters
  • Easy, quick and accurate depth measurements; no conversion - table required for sonde depth measurements
• Measures signal current in cable
  • Helps identify target cable regardless of depth
• Visual and audible cable locates
  • Ensure accuracy under varying field conditions
• Coupler jack
  • Pair/cable identification
• Graphic display
  • Operator can distinguish between target cable and other cables in congested areas
• Expander function
  • Improves sensitivity of audible and visual response
• Three passive 50/60 Hz frequency settings
  • Optimized for primary, secondary, or rectified power
• 31.5 kHz Auxiliary frequency
  • For locating CATV cables
