3M 2273E - Manual (Page 3)

INTRODUCTION
The 3M ™ Dynatel 2250E/2273E Advanced Cable and Fault Locator
consists of a Transmitter and a Receiver for locating buried cables or
Active Duct Probes (sondes). It also measures and pinpoints sheath faults
in buried cables (2273E only) and conductor faults in aerial cables. The
transmitter provides four frequencies to accommodate varying factors such
as distance, cable type, or soil conditions. If desired, all four frequencies
may be transmitted at once. The Transmitter also provides a separate Tone
function for identifying cables and pairs. The Receiver provides four
locating modes to accomplish fast or difficult tracing and to pinpoint or
verify a conductor. The Receiver detects 50 or 60 Hz AC Power signals and
low frequency (LF) radio signals re-radiated from local broadcast
transmitters. It also measures the signal current in a conductor and displays
its magnitude. The depth of buried cables or sondes may also be displayed.
Note: For more detailed locating instructions and advanced locating
techniques, ask your 3M sales representative for a free publication called
Cable and Pipe Locating Techniques.
