3. MAIN APPLICATIONS - TIP SENSOR (De-Energized)
Using AT-8000-R Receiver in De-energized TIP SENSOR mode
TIP SENSOR
De-energized TIP SENSOR mode is used for general wire tracing, pinpointing wires in bundles,
tracing in tight corners and confined spaces such as junction boxes or inside enclosures.
1. Press power button to turn on the Receiver; home screen may take up to 30 seconds to load.
2. Select De-Energized TIP SENSOR mode by using the directional arrows and pressing the
yellow ENTER button.
3. Hold the Receiver with the Tip Sensor facing the target area.*
4. Scan target area with Tip Sensor to find highest signal level (Figure 3.2c). While tracing,
periodically adjust sensitivity to keep signal strength near 75. Increase or decrease
sensitivity by pressing + or – on the keypad. If signal is too strong for precise locating,
change transmitter to LOW mode.
5. Press ENTER when complete to return to the home screen.

*Note: For best results, keep the Receiver at least 3 feet (1 m) from the Transmitter and its
test leads to minimize signal interference and improve wire tracing results.
De-energized mode uses a different antenna in the Tip Sensor than Energized mode.
Specific alignment of the Tip Sensor groove to the wire is not required. De-energized wire
tracing results are based only on how close the Tip Sensor is to the wire.
3.3 Identifying Breakers and Fuses
Breaker mode automatically adjusts the sensitivity of the Receiver. As a result, the Receiver
will pinpoint and indicate just one correct breaker/fuse. This enhancement helps to remove
signal strength analysis from the breaker/fuse identification process that is typical for less
advanced wire tracers.
Note: For breaker/fuse locating, a simplified direct connection to hot and neutral wires can
be used because these wires are separated at the breaker/fuse panel. There is no risk of
signal cancellation effect if wires are at least a few inches away from each other. However,
the separate ground connection (Figure 3.3b) should be used for superior results specifically
if wires need to be traced in addition to breaker identification.
The simplified direct connection to hot and neutral wire will NOT trip the GFCI circuit.
