Ultra-Trac APL Instruction Manual General Description The Ultra-Trac® APL is an acoustic pipe locator designed to locate piping systems constructed of any material including (but not limited to): plastic, metal, clay, concrete, fiberglass, cast and ductile iron. The piping systems can also be located regardless of the type of surface above the pipe such as gravel, soil, grass, concrete or asphalt.
Principle of Operation The Ultra-Trac® APL locates pipe through acoustic impedance mismatch. The speed of sound through ground materials differs from pipe material. This makes the pipe detectable using the Ultra-Trac® APL. The acoustic wave pattern of specific timing and frequency is monitored and processed using the device’s accelerometers.
Control Tablet and Mount Features The control tablet is mounted at the end of the Display handle and is positioned so the display, on/off Speaker button, speaker, charging indicator and scan button are directed toward the user. On/Off Button Charging Indicator Scan Button Chassis Features...

Operation of Instrument 4. Prepare to take measurements (Scan View) Once both the chassis and tablet are on and the tablet has the APL application displayed, press the soft button “Connect to APL”. The tablet will take a moment to connect, when the connection is established the button will turn green and display the message “APL Connected”.

Operation of Instrument 6. Prepare to Take First Reading Observe the sensor status in the upper right corner of the display. This indicates the accelerometers are ready for a reading. The sensor status should read “OK, OK” indicating that both accelerometers are functioning properly.
Scan View Feature Details Scan View Scan view is the default operating mode and is useful for collecting and viewing raw data in real time, and is used to mark locations in the field. Connect to APL/APL Connected Same button depending on the state of the APL. Connect to APL: Establishes communication between tablet application and the APL base.

Supervisor Settings Menu The Supervisor Settings should not be changed without first consulting the manufacturer. The Supervisor Settings Menu contains adjustments for how the APL analyzes the received signals. Supervisor Menu is password protected. Region of Interest (ROI) First, there is the Region of Interest (ROI). This adjustment consists of four settings, ROI Start and ROI End, ROI Start (Deep), and ROI End (Deep).

Depth Chart A time measurement (in milliseconds) is displayed on the ‘Y’ axis of the display. The APL measures the time it takes for the acoustic signal to travel from the APL actuator to the underground object and back. This will assist in identifying objects at similar depth. Consult the APL Time Conversion Chart (below) for approximate depths.
What to avoid When testing, always perform a scan on surfaces of like material. A scan requires a minimum of 5 slices on pavement, gravel, grass or dirt. Do not perform 12” scans on Do not mix surface types in a Do not perform a slice on large loose or freshly excavated soil.

Performing a Locate g. Move the selected direction and distance corresponding to the measuring tape on the ground (6 or 12 inches). h. Continue to perform the desired number of slices to perform the scan. A minimum of 5 slices is required. There is a maximum of 26 slices per scan. When completed, press the “Plot”...
Maintenance The Ultra-Trac® APL is designed to be relatively maintenance free. It is important to keep the actuator and accelerometers clean of mud and debris. Good results are the result of good coupling with the ground and using consistent procedures. In the field it is important to: •...
