5.6 Advanced Data Processing, Depth Slices, and 3D Views

The EssGpr4LoggingApp does not have the capabilities to generate depth slices or 3D

views of the subsurface. To generate these views, use the companion program

ESSentialUnderground that is distributed with the system.

5.7 Charging the Batteries

There are three rechargeable batteries in the system that provide sufficient power for

operation over a full day. The battery in the scanner unit provides power for about 8 hours. A

second battery is provided so that surveying can continue after the first is depleted.

Additionally, the Microsoft Surface Pro 4 tablet contains a battery that will provide 5-8 hours of

continuous operation depending on screen brightness settings. The shipping container contains

an integrated battery charger that can simultaneously charge all of the batteries with only a

single external power connection. The system is designed to be charged overnight so that all of

the batteries are ready for use during the work day. To charge the batteries, follow these steps.

1. Switch off the scanner unit.

2. Remove the battery from the scanner unit and place it in one of the scanner

battery charging ports in the shipping case. Place the spare scanner battery in the

other charging port.

3. Connect the tablet charging cable to the tablet computer.

4. Plug the main charger power cable into 120/220 VAC mains power.

5. All batteries should charge in 6-8 hours, and all of the charge indicator lights will

be green when all of the charge cycles have completed.
