The 3MT DynatelT Cable/Pipe Locators 2250M/2250M-iD require
very little operator training. An RS232 communications port allows
interface to an external computer for uploading/downloading of
data, unit configuration and remote software upgrades. Estimated
operating time is more than 30 hours on eight AA alkaline batteries.
The 3MT DynatelT 2250M-iD Cable/Pipe Locators are designed
with even more functionality than the 2220M models, and iD versions
have the enhanced capability to read and write user information
into the 3M EMS iD markers.
The 2250M/2250M-iD locators use four active trace frequencies (individually
or simultaneously) to compensate for varying field conditions.
The receiver incorporates passive power, CATV, and auxiliary
frequencies that do not require the use of the transmitter. The receiver
also offers four user-definable auxiliary frequencies.
