    UtilityScan DF Quick Start Guide Page 54 Appendix C: Glossary of Terms Dielectric: A value assigned to materials and is used to calculate the velocity of RADAR in that material. RADAR will travel at different speeds depending upon the material and/or soil condition. RADAR travels fastest in air (dielectric = 1) and slowest in water (dielectric = 81).

By selecting a value of 3, 5, 9, or 15, the process with take each scan and replace that scan with the average values of the surrounding scans. Be aware that too much stacking can filter out real targets.

  • Page 64: Appendix D: Connect And Configure Gps

    Appendix D: Connect and Configure GPS The UtilityScan DF is designed to work with a wide variety of GPS units. In order to operate with the UtilityScan DF, your GPS must be able to output the NMEA GGA string through a 9-pin serial port. The GPS data are saved in a separate file with the same root name as your GPR data file.
  • Page 65 The UtilityScan DF performs a constant quality check on the incoming GPS stream. This is visible at the lower left-hand corner of the screen. The UtilityScan DF checks the HDOP once per second. A high quality HDOP, 2 or less, is required for the system to record GPS data.
