Set-up Transmitter either Inductively or Conductively

Inductive

Be aware of air coupling, the transmitted signal travelling

to the Receiver via the air, not the utility.

Conductive

Connect the ground plate/ground rod assembly to the trans-

mitter. Connect the red lead to the non energized utility. Con-

nect the black lead to the ground plate/ground rod. Place the

plate/rod at a 90 degree angle in reference to the utility. Be

sure not to place the wires over any other utility.

After transmitter set-up, move away from the point of con-

nection (or Induction) about 25 feet (8 meters). Sweep a

circle around the point of connection. Initially, disregard

the LEFT/RIGHT indicator and rely on the signal strength

readout. Make note of the high readings. These are areas

that need to be traced/examined in more detail.

Tracing

After locating the point(s) where the signal strength was

the highest, return to that/those points and start tracing

your utility. This is where the LEFT/RIGHT indicator is

very helpful. Swing the receiver from left to right and lis-

ten for the change of tone. When the target is to the RIGHT

of the receiver, the tone is pulsed tone. As the receiver

gets closer to the target, the pitch gets higher. When the

target is to the LEFT of the receiver, the tone is a continu-

ous tone. As the receiver gets close to the target, the pitch

also becomes higher. When the receiver is over the target,

OVER TARGET is displayed on the display screen, and the

tone is at its highest peak sound.

Depth Measuring

When an OVER TARGET response is displayed, position

the blade of the receiver directly over the utility and

place the tip on the ground. Hold the receiver steady,

press and hold the DEPTH pad. Depth will be measured

to the center of the utility.

OPERATING INSTRUCTIONS

The following instructions are designed for a safe and effective

method of line tracing and utility avoidance. Some of the steps

may not be applicable in all situations. The underlying guideline is

that operator safety must be maintained at all times. Use of

safety equipment, extra personnel, and up to date as-built plans

should be considered when necessary.
