GPR4 Utility Scanner – User Manual Earth Science Systems, LLC D-000002-000023 October 9, 2019 4 Introduction 4.1 Overview This document provides the operating and configuration instructions for the Utility Scanner. The Scanner locates subsurface objects and utility lines such as such as pipes, conduits, and vaults, and can locate defects such as voids. The scanner can produce simple cross sections, depth slice images, or 3D images of the subsurface.

To conduct a survey, proceed as follows. Copyright © 2019 ESS, LLC.
GPR4 Utility Scanner – User Manual Earth Science Systems, LLC D-000002-000023 000023 October 9, 2019 1. Turn on the power to the sensor unit. The power switch should glow with a green light. After a few seconds the light will begin to flash rapidly – indicating that it is searching for the least congested WiFi channel channel. The light will stop blinking after the search completes (about 60 seconds). 2. Boot up the tablet computer and log in.
GPR4 Utility Scanner – User Manual Earth Science Systems, LLC D-000002-000023 October 9, 2019 e. Depth/Time range Users can opt to display the full range, half range, quarter range, or eighth range. Users may wish to display only a shallow portion of the usable range when interested in the more shallow portions of the surveyed range (depth). f. Velocity of medium The velocity of EM waves is dependent on the material type.
