2. About This Manual
There are two basic models included in the 3M Dynatel Locator 2500 loctor Series. The
2550 is designed for pipe/cable locating. The 2573 loctor is designed for cable/pipe and
fault locating. The iD option (read/write capability to 3M
™
iD Markers) is available for
both models. The 2550/2573 Series transmitters are 12 watt units. They provide .5 watts, 3
watts and 12 watts of output power. 12 watts is attained by utilizing the Cigarette Lighter
Adapter or External Rechargeable Battery. This instruction manual will include all features.
All instructions are applicable to all products, unless noted.
The 12-watt transmitter offers additional power output levels for improved induction
performance and 8 kHz (low frequency) induction for shallow facilities, such as risers.
The maximum output power in Direct Connect method is reduced to comply with FCC
limits. (FCC limits: 10 watts at 33 kHz and 1 watt at 82 kHz and 200 kHz)
In order to demonstrate all available functions, some illustrations depict the 2573-iD
receiver unit. The 2550 receivers and transmitters may vary from the illustrations shown.
