Transmitter for utility locating, 5 Watt, Loc3 series

The 5-watt broadband transmitter offers selectable induction and direct connection frequencies from 98Hz to 200kHz, SD mode (signal direction), fault find and true resistance measurement up to 1 Mohm. The 2 x 1 inch dot matrix display with LED backlight shows output current, connection type, volts, resistance, frequency, volume, battery condition and high-voltage warnings.

The optional transmitter link (Tx-Link), installed in both receiver and transmitter, allows the transmitter to be operated remotely from the receiver. The range of the radio link depends on having a clear line of sight between receiver and transmitter, and is typically around 300m.

Signal direction (SD) mode

This feature verifies whether the line being located is the target the transmitter is connected to. When a transmitter is connected to a target line, the signal travels along it and finds the easiest way to travel back, usually via the ground and the ground stake. Very often, however, the signal travels back along adjacent utilities which offer an easier route. As a result, there can be multiple signals radiating from utilities in the area, making it difficult to identify the target line. These return signals typically travel in the opposite direction to the applied signal. The signal direction feature identifies which way the signal is flowing, and hence the target line.

Packaged in a lightweight, rugged, ergonomic IP54 housing, the transmitter provides consistent current output in direct connect, clamp and induction modes, plus protection against inadvertent connection to incoming voltages up to 240V.
