Low Power 4 hours

Medium Power 2 hours

High Power 1 hour

Battery Check

At start-up, the ST-305 will check available power and will

indicate estimated battery levels by lighting one, two, or

three LEDs in the right hand column (power level) on the

control panel. These levels are only estimates based on a

rapid internal check. A rapid series of beeps will sound if the

battery levels run low in operation.

Direct Connect – The transmitter’s leads are connected

directly to the target conductor and a suitable ground.

The ST-305 line transmitter can apply an active tracing signal

The ST-305 is capable of dual-frequency transmission

to a target conductor in three ways:

(sending two frequencies onto a line simultaneously) in

direct-connect mode. See page 7.

Inductive Clamp – The jaws of the inductive clamp encircle

the target conductor; there is no metal-to-metal contact.

(The inductive clamp is an optional accessory). See page 7.

Inductive Mode (internal coils) – The transmitter is placed

over, and in-line with, a conductor. Its internal antenna

generates a dipole eld which energizes the target conductor

below ground, inducing a current into the target conductor.

See page 8.

DANGER! Always connect leads before turning the

is well grounded.

Insert the ground stake into the ground. Connect one of the

cable leads.

Useful Operating Tips

Inductive Clamp Method

• The lower the resistance, the more current will be put on

the line.

• Scrape away dirt, paint, and corrosion before connecting

to the target conductor or to the grounding spike.

• Insert the grounding spike as far as possible. Eventually

try wetting the area if necessary.

• Keep the transmitter leads short by stowing the excess

length on the transmitter’s body. This will reduce the

amount of interfering signals from the leads. Where

possible, place the transmitter away from the area of the

intended locate. This is especially true in Inductive Mode,

to avoid coupling through the air with the receiver.

• Start by using the lowest frequency and the least amount

of current needed to eectively illuminate the line. Lower

frequencies travel farther because they do not dissipate

1. 93 kHz only (rapid ashing 33kHz LED).

2. 33 kHz and 1 kHz dual-frequency transmission

(LEDs for 33 kHz and 1 kHz both lit).

3. 33 kHz and 8 kHz dual-frequency transmission

(LEDs for 33 kHz and 8 kHz both lit).

Dual-Frequency transmission is available only in direct

connect mode.

The advantage of dual frequency is that you combine the

advantage of a lower frequency (less risk to bleed over,

longer distance) with the advantage of the higher frequency

(a higher frequency can “jump” over small hurdles allowing

to continu the trace). Thus you start locating at a lower

frequency and when the signal stops due to eg a rusted valve,

you can switch to a higher frequency without the need to go

back to your transmitter and set the frequency at a higher

frequency.

1. Be sure that the transmitter is positioned correctly

over the line.

Guide

Figure 11: ST-305 in Inductive Mode at 33 kHz

4. Lower frequencies couple poorly. Therefore, the

ST-305 transmitter in Inductive Mode defaults to

33 kHz. Higher power is usually required for a clear

signal in Inductive Mode. Pressing the power key will

cycle through the three available power levels: 1 kHz,

8 kHz, and 33 kHz.

NOTE: If using the ST-305 in Inductive Mode, be certain to

switch Inductive Mode o if you are going to use the unit in

direct connect mode. Air coupling can create very confusing

signals if you inadvertently have the unit set to Inductive

Mode and are trying to use it in direct connect mode.
