Dynatel 2273 Cable / Fault
Locator
The 3M Dynatel 2273 Cable/Fault
Locator is amicroprocessor-based system that
incorporates advanceddigital signal processing
techniques to quickly andefficiently locate sheath
(earth return) faults and trace thepath of
underground cables, both copper and fiber optic(with
metallic trace wire). Lightweight, compact and well-balanced,the
2273 cable/fault locator accurately:
-
Locates cable path
-
Measures cable or sonde depth with the
push of a button
-
Measures signal current in the cable
-
Pinpoints sheath faults and cable
breaks
-
Discriminates between light and heavy
faults
-
Identifies cable and cable pairs
-
Tones shorts and grounds in aerial
cable
-
Identifies cable pairs through wet
sections
-
Locates energized power cable
The 2273 cable/fault locator provides
accurate cable orsonde depth measurements, giving a
digital readout ininches, feet and inches, or
centimeters (user-selectable).
