The Metrotech Model 480B Pipe and Cable Locator is a versatile instrument designed for locating and tracing the path of pipes and cables, detecting energizing 60Hz power lines, and, when mounted on an optional carrying handle, conducting blind searches, ground surveys, and locating underground metal masses. Depth measurement is achieved using the triangulation method. The 480B features a split-box design, with half serving as the Transmitter and the other half as the Receiver.
The Transmitter generates a signal that is applied to the conductor to be traced. This signal travels along the conductor, becoming weaker as it moves farther from the Transmitter. The distance the signal travels before becoming too weak to be detected depends on the connection method, conductor type, surrounding soil, and conductor depth. When the Receiver is positioned over the target conductor, it detects the signal, allowing the operator to trace the path of the pipe or cable. The signal strength reading on the meter and the audio tone guide the operator to the conductor's path. As with all electromagnetic locating systems, this unit is designed to locate metallic conductors only.
The 480B Pipe and Cable Locator offers three methods for applying the signal to the conductor: Direct Connection, Inductive Coupling, and Inductive (Indirect Method). Additionally, there are two methods – PEAK and NULL – for locating the conductor.
The Model 480B is designed for rugged outdoor use, but rough handling should be avoided. Keeping the equipment dry, clean, and free of grit is recommended.
Metrotech warrants its equipment to be free from defects in workmanship and material under normal and proper use and service for one year from the date of purchase by the original user. The warranty does not cover equipment altered or repaired by non-Metrotech approved procedures, misuse, misapplication, improper maintenance, negligence, accident, or if the serial number is altered/removed. Batteries, fuses, and lamps are excluded. Defective products under warranty will be repaired or replaced free of charge at a Metrotech Corporation factory or approved repair station.
