SECTION I: GENERAL
Introduction
The TraceMaster
is the first pipe and cable locator on the market to offer a Remote Link between the
transmitter and the receiver units. This is accomplished through a radio frequency (RF) two-way
communications channel, and makes it possible to change the transmitter frequency from the receiver. The
link also allows the receiver to monitor the transmitter battery status and other operating parameters.
The TraceMaster
operates on a passive mode, three different active modes (conductive, inductive and
clamp), and a sonde mode. In the passive mode the transmitter shuts down its output and the receiver
searches for 50/60 Hz signals. In the active modes the transmitter operates at a low frequency (575 Hz), a
mid-range frequency (8 kHz), a high frequency (82 kHz), and a very high frequency (455 kHz). In the
sonde mode the receiver searches for the signal transmitted by a small sonde (either 512 Hz or 82 kHz) that
has been routed through a pipe. The choice of frequencies depends on the specific active mode, as
explained elsewhere in this manual. In addition, the receiver can determine the approximate depth of the
target, and has the ability to operate in manual or automatic gain modes.

Receiver
The receiver's front panel is designed to be intuitive and require a minimum of training for effective use of
the instrument. The controls and the information display area are large and easy to understand. Yet they
include everything necessary to control and monitor the transmitter remotely.
Controls
MASTER ON/OFF SWITCH - This switch is built into the VOLUME control. When the VOLUME
control is in the full CCW position, past its “click”, power to the unit is removed, and the ON/OFF
TRIGGER SWITCH is disabled. The intention of this switch is to prevent accidental turn on by depression
of the trigger switch when the unit is stowed away.
ON/OFF TRIGGER SWITCH - The trigger switch is located in the handle of the receiver and it applies
power when the unit is picked up and held by the handle. When the trigger is released (the receiver is put
down or stored away), the power is removed from the instrument. There is a 5-second delay to prevent
premature power removal when changing hands or letting the handle go momentarily. This switch helps to
conserve battery power by preventing the user from leaving the power on accidentally.
NOTE: The trigger switch is enabled by the MASTER ON/OFF switch built into the volume control (see
description above).
VOLUME - The volume control adjusts the volume of the tone coming from the speaker. The volume
increases as the control rotates in the CW direction.
