5. Connect the RED test lead to the conduc-
tor to be tested.
6. Press the ON/OFF button to turn the trans-
mitter ON. When the transmitter is turned
on, it is set to the last used frequency.
Press the frequency selection button to
cycle through frequency settings to the
desired locating frequency.
Adjust the signal power by pressing the
signal power button to cycle through the
settings (low, medium and high). Using
high power can couple into non-target
conductors, low power may mean a circuit
is not created. The transmitter will display
circuit resistance (OHMS) at the bottom of
the LCD. The lower the resistance the bet-
ter the locate signal. To improve the circuit,
improve the ground, check the lead con-
nections, increase power or change the
frequency.
If the transmitter display shows voltage
warning (Figure 3), the transmitter is con-
nected to live voltage. If this happens,
DO NOT TOUCH THE TRANSMITTER,
LEADS OR CONNECTIONS. The tar-
get conductor is energized and there is
the risk of electrical shock. Use high volt-
age precautions to disconnect.
7 . Check the circuit and adjust signal power,
grounding or connections to ensure locat-
able field.
8. Turn ON the receiver/locator and follow
the instructions for the receiver. Make sure
the receiver's frequency is set to match that
on the transmitter. Confirm the receiver is
picking up the transmitted frequency by
holding it near the transmitter and observ-
ing the increase in receiver signal.
9. Once the locating is completed, press the
ON/OFF button to turn the transmitter
OFF. Always turn the unit OFF before dis-
connecting the cable leads to reduce the
risk of electrical shock. Remove the cable
lead from the target conductor first. Always
disconnect the cable lead from the target
conductor first before removing the cable
lead from the ground spike to reduce the
risk of electrical shock. Disconnect the
cable lead from the ground spike.
Inductive Clamp Path
Locating
1. This method requires an inductive clamp
(Optional equipment). Read and follow
12
all instruction for the use of the inductive
clamp.
2. Insert the plug of the inductive clamp
into transmitter (see Figure 2).
3. Clamp the jaws of the inductive clamp
around the target conductor. Make sure
that the jaws of the clamp are fully closed.
(See Figure 14). Both ends of the conduc-
tor should be grounded for best results.

Conductor
4. Press the ON/OFF button to turn the trans -
mitter ON. When the clamp is plugged in
the clamp symbol (
screen and only clamp frequencies are
available. Press the frequency selection
button to cycle through frequency settings
to the desired locating frequency. Adjust
the signal power by pressing the signal
power button to cycle through the settings
(low, medium and high). The inductive
clamp typically works best with frequen-
cies around 8kHz, 33 kHz, 93kHz.
5. Check the circuit and adjust signal strength
(see Figure 3, Circuit Information).
6. Turn ON the receiver/locator and follow
the instructions for the receiver. Make
sure the receiver's frequency is set to
match that on the transmitter. Confirm
the receiver is picking up the transmitted
frequency by holding it near the trans-
mitter and observing the increase in re-
ceiver signal.
7 . Once the locating is completed, press
the ON/OFF button to turn the transmitter
OFF.
Broadcast Inductive Path
Locating
1. Properly place the transmitter relative to
the target conductor (see Figure 15). On
the top of the transmitter is an arrow. Set
