Introduction
Congratulations! You have just purchased one of the nest, most
advanced locating devices available today! When you choose a
quality 3M™Dynatel™Advanced Pipe/Cable Locator 2220M, you
get outstanding performance andreliability.
The 2220M locator with the 3-watt transmitter is an excellent
instrument for tracing underground utilities. The 2220M provides
one audio frequency for locating long sections of cable and one radio
frequency for tracing pipes that may have high resistance insulators
and rubber gaskets that are often found in water and gas distribution
systems. The 2220M also provides three sonde locating frequencies.
The 2220M locator with the 12-watt transmitter* option oers
additional power output levels for improved induction performance,
8K (low frequency) induction for shallow facilities, such as risers, and
an ohm-meter function for measuring path resistance.
* Output Power up to 12 Watts for the 12 Watt Transmitter is achieved using the supplied
external power source. 12 Watt Output Power varies by frequency, or is limited to 1 Watt
at 82 kHz on the U-Model using direct connection method.
