4. SPECIAL APPLICATIONS
Connecting the Signal Clamp
1. Connect the CT-400 test leads to the terminals of the Transmitter (polarity does not
matter).
2. Clamp the CT-400 Signal Clamp around the conductor. To increase the signal strength,
wind a few turns of the conductor wire around the clamp if possible.
Setting up the AT-6000-T Transmitter
1. Press the ON/OFF key to turn on the Transmitter.
The red LED voltage status indicator should be OFF
when the clamp is connected and when working
with either Energized or De-energized systems.
2. Press HIGH signal mode and hold
pushbutton for >2 seconds to select the
Loop mode on the Transmitter. The clamp
mode generates a boosted 6 kHz signal in order to
provide superior tracing results. The screen on the
Transmitter should appear as in Figure 4.12b.
Using the AT-6000-R Receiver
1. Press the ON/OFF push button to turn on the Receiver.
2. Select either Quick Scan or Precision Tracing mode.
3. Hold the Receiver with the Tip Sensor facing the
target area.
4. Scan the target area with the Tip Sensor to find the highest signal level. While tracing,
periodically adjust the sensitivity to keep the signal strength near 50. Increase or
decrease the sensitivity by pressing + / - on the keypad.
5. Receiver Positioning: For best results while tracing Energized wires, align the groove on
the Tip Sensor with the wire direction as shown. The signal may be lost if not properly
aligned.
6. To verify the wire direction, periodically rotate the Receiver 90 degrees. Signal strength
will be highest when wire is aligned with the Tip Sensor groove.
