back through the ground to the transmitter ground stake. The current flow
through the earth is measured by probing the ground along the cable path
with the receiver "A" Frame. Since the current is directional, the receiver meter
pulses or kicks with each transmitter pulse in the direction of the fault. The
fault will be located midway between the receiver "A" Frame probes when the
receiver meter indication nulls.
2. OPERATION
1. Start at either end of the faulted conductor. Remove the power from the
conductor under the test and disconnect all loads to prevent damage from
high voltage and false readings.
2. With the transmitter off, connect the clip of the black transmitter lead to the
ground stake. Insert the ground stake deeply into the earth.
(See Figure 1.)
3. With the transmitter off, attach the receiver to the "A" Frame and connect
the "A" Frame receiver leads to the receiver input jacks – the black lead to
the black jack and the red lead to the red jack. (See Figure 2.)
4. Turn the transmitter on, and pulses will commence after a short delay at
approximately three second intervals as evidenced by the transmitter
beeper.
Do not handle transmitter leads, clip, or conductor under test when
the transmitter is on. Failure to observe this warning will result in
severe injury or death.
5. Turn the receiver on. Verify the battery condition by pressing the battery
test button and observing the meter. Insert the "A" Frame probes into the
earth. (See Figure 3.) If all probes are making good ground connection, the
receiver will kick toward the fault (away from the transmitter) in step with
the transmitter beeper.
