SeekTech ST-510 Line Transmitter
measure this field instead of on the target
conductor. Place the transmitter at least 20
feet away from the region where tracing
occurs in order to avoid this "air coupling".

6. Generally if you trace a line with an induced
signal checking for a valid depth measurement
and a strong stable proximity signal is the best
way to confirm that you are locating the
induced signal in a line and not the signal
directly from the transmitter through the air (air
coupling).
Note:
If you have been using the ST-510 in
inductive mode, be certain to switch inductive mode
off 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 but are trying to use it in direct
connect mode.
Features
48' (16m) Coil Cords (Extended)
The leads of the ST-510 are specially designed,
hybrid copper and stainless steel, aircraft-grade
coiled cables. They can be stretched out to offer
more freedom in choosing grounding points and
connections to the line. The further out they are
extended, the more incidental signal they can send
out; accordingly, the receiver should be used further
away from the transmitter to avoid being misled by
the cords acting as antennas.
Figure 20: Storing Leads: Right Way and Wrong Way
To avoid tangled cords, "feed" the cords back into the
pockets when storing, lead end last.
Note: Avoid over-stretching the coil cords as they
may not fully retract, and become difficult to store in
pockets. They can extend to 48' (16m) readily. If
they are extremely warm they may take a while
longer to contract fully after full extension.
Auto Back Light
The SeekTech is equipped with an automatic LCD
backlight. Whenever a key is pressed, the backlight is
activated to aid viewing for 80 seconds.
High Voltage Indicator
When ever the line transmitter encounters voltage
higher than about 42 volts (RMS), it will flash a red
LED at the bottom of the keypad. The LCD will
display "High Voltage". If this occurs, follow high-
