3. MAIN APPLICATIONS - TIP SENSOR (De-Energized)
Using AT-7000-R Receiver
1. Press 'ON/OFF' push button to turn on the receiver and wait for the home screen (boot
up time is around 30 seconds).
2. Select De-Energized TIP SENSOR mode by using the directional arrows to highlight this
operating mode and pressing the yellow "ENTER" button. Screen will appear as shown
in Figure 3.2c
3. Hold the receiver with the Tip Sensor facing the target area.*
4. Scan target area with Tip Sensor to find highest signal level. 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 Home screen.
*Note: For best results, keep the receiver at least 3 feet 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 in 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.
