3M 2273E, 2250E manual Introduction, Installing or Replacing the Batteries

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.
