5. Clamp the jaws of the inductive clamp around the tar-
get conductor. Make sure that the jaws of the clamp
are fully closed. (See Figure 12).

6. Turn the transmitter on and select a frequency for lo-
cating, check the circuit and adjust current. (See
page 11). Be sure that the receiver is set to the same
frequency. The inductive clamp typically works best
with frequencies around 33 kHz.
7. Once locating is complete, turn the transmitter power
OFF before disconnecting the clamp.
Inductive Mode
1. Properly place the transmitter relative to the target
conductor. On the top of the transmitter is an orien-
tation mark. The orientation mark needs to be aligned
with the target conductor. (See Figure 13).

6. Select a frequency, check the circuit and adjust cur-
rent. See pages 10 and 11 for more information.
7. 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 re-
ceiver is picking up the transmitted frequency by
holding it near the transmitter and observing the in-
crease in receiver signal.
8 Once the locating is completed, press the POWER
ON/OFF button on the keypad to turn the transmitter
off. Always turn the unit off before disconnecting
the cable leads to reduce the risk of electrical
shock. Remove the cable lead from the target con-
ductor 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. Store the cables and ground spike for trans-
portation.
Inductive Clamp Method
1. This method requires an inductive clamp that is not
supplied with the transmitter. Read and follow all in-
struction for the use of the inductive clamp.
2. Confirm that the target conductor is NOT energized
(live). The transmitter is not designed to be con-
nected to energized (live) conductors.
3. Confirm that the transmitter is OFF. If needed, press
the POWER ON/OFF button on the keypad to turn
the transmitter off. Never turn the transmitter on before
attaching the inductive clamp.
4. Insert the plug of the inductive clamp into the jack on
the transmitter (above the battery holder). When the
inductive clamp plug is in place, the transmitter will au-
tomatically be in Inductive Clamp mode, the cable
leads will be disabled, and “Clamp” will be displayed
on the screen. (See Figure 11).
