Power and Radio mode location
Note: After completing a power mode sweep we recommend that
you repeat the procedure in radio mode; the procedure is the same.
Power mode
Power mode detects power signals radiated by loaded power cables.
To select Power mode, rotate the function switch until the LCD displays
a P icon. Rotate the sensitivity control fully clockwise for maximum
sensitivity but reduce if there is a blanket signal across the site. Define
the excavation site and carry out a grid pattern sweep. Note that
sometimes the signal may be re-radiated from other conductors.
Sweep the site holding the Su upright at your side.
Continue the sweep beyond the perimeter of the site. The presence of
a buried conducting pipe or cable will be indicated by a tone emitted
from the loudspeaker and a kick on the LCD’s bar graph.
Keep the Su blade vertical and move slowly backwards and
forwards over the conductor. Reduce the sensitivity for a narrower
response; this will allow you to pinpoint the conductor. With the
Su use the meter deflection to aid pinpointing. Maximum
meter deflection and audible volume from the speaker will indicate the
position of the conductor.
When directly over the conductor and with the sensitivity level set for
a narrow response, rotate the Su on its axis until the signal
minimum is found. The blade is now parallel with the conductor.
Trace the conductor beyond the site and mark the position as required.
Radio Mode
Radio mode detects broadcast signals that originate from radio
transmitters. These signals penetrate the ground and are re-radiated
by buried conductors. However, depending on your location, these
signals may not be present.

™
The Strike
Alert
feature warns the operator of shallow pipes and
cables.
When a shallow cable or pipe is detected in Power or Active line Mode,
Strike
Alert
flashes an asterix and sounds a distinctive warbling audio
tone. Strike
Alert
is not activated when tracing sondes or Radio signals.

T1 – 1W transmitter
The T1 is a general purpose, 1 Watt, transmitter that provides three
locatable frequencies, two induction frequencies and two power
levels. By default, the T1 induces a signal directly into the ground.
It is the perfect companion to the Su range of cable and
pipe locators.
Transmitter features
1. On/Off/Frequency Selector.
LEDs indicate which frequency
has been selected.
a. First press switches the
transmitter on and selects
the lowest locate frequency
– depending on product
specified. See T1 transmitter
range table.
NOTE: the lowest frequency is only available for direct connections
and will not work in induction mode.
b. Second and third presses select the mid and highest frequencies.
c. Fourth press turns the transmitter off.
2. Power Selector
Selects either high or low power level. LEDs indicate which
power level is active.
3. Accessory Socket
Connects cables or optional accessories such as the Signal
Clamp, Direct connection lead or Live Plug Connector.
When connected, induction mode is disabled. A loudspeaker
emits a pulsing tone to indicate sufficient battery charge and
a satisfactory direct connection.
4. Battery Access Panel.
When no tone is audible the batteries
must be replaced.
5. Arrows
The arrows on the top panel label indicate the required transmitter
alignment above the pipe or cable when using Induction mode.
The arrows and the pipe or cable must be parallel. Alignment is
not required when the T1 is in Active mode.
Note: Turn off the T1 and remove any cables or accessories
before changing batteries.
