4.4. Voltage, Resistance and Output Current Measurements Using the Transmitter

Refer to Page 9 Transmitter Settings Menu Functions for details.
4.5. Advanced Locating Techniques – Two Person Swap
1. Set up the Transmitter as described in the Induction Mode – Locating Utilities section 3.4.
2. Turn the Receiver on by pressing the power button for two seconds and select 33 kHz frequency by pressing
button.
3. Select the area to be checked. One person holds the Transmitter with the handle in line with the direction of
movement and the other holds the Receiver (as shown below).
4. Stand at least 15 feet (5 m) apart holding the equipment as below, with the Transmitter and Receiver in line
with the direction of movement.
5. Adjust the sensitivity of the Receiver so that the meter reads approximately 20% signal strength.
6. Walk slowly across the site keeping parallel with each other. As a service is approached, the signal level on
the Receiver will increase. When the signal is at a maximum, stop the Transmitter and place it on the ground.
Then pinpoint the position of the service with the Receiver as described in the Receiver Locating section 3.1.
Mark this position and plot the route across the site if necessary.
7. Continue to the sweep across the site and then, if possible, repeat the process at 90 degrees to the sweep
already completed.

4.6. Locating Faults with the AF-600 A-Frame Accessory

The AF-600 A-Frame cable ground fault finder is an optional accessory specifically designed for the Amprobe
UAT-600 series. In combination with the Transmitter, it will pinpoint the place where a cable metal conductor
(either a sheath or a metallic conductor of the wire) touches the ground. It can also detect other conductors to
ground faults such as pipeline coating defects. Refer to the AF-600 A-Frame user manual for full instructions.
