Warning and Alerts Descriptions
ALERT
Alert Description
DM current warning - will appear in the Info screen when the current change exceeds a pre-determined value.
Signal Overload - is usually caused by operating close to power transformers or being close to a transmitter in
Induction mode. Moving away from the interfering signal will cure the problem.
Shallow Cable - alerts indicate that the locator has detected a possibly less than 15cm (5.9-inch) deep cable.
Proceed with caution.
Swing Alert - indicates that the operator is swinging the locator excessively resulting in misleading information.
When sweeping the locator across the direction of the line try to keep it vertical as this will improve its accuracy.
Overhead Cable - alerts indicate that the source of the signal is mainly radiating from above. This alert is
usually caused by the signal traveling along overhead cables.
3.7.2
DFT (Discrete Fourier Transform)
DFT is a tool to assist in choosing a frequency to apply to the target conductor. The DFT feature will aid the user with nearby
interference that may affect the locate quality.
*Note the DFT feature should not solely be used to determine which frequency to apply. ALWAYS
follow the appropriate safety requirements mandated by safety legislation, safety practice or your
company’s safety procedures when applying a locate frequency to a conductor.
1. To perform a DFT assessment verify any nearby transmitters are powered off to avoid additional signal frequency
disturbance.
2. Select your preferred frequencies from the frequency menu. These selected frequencies will be assessed in the next few
steps.
