Survey

After setup is complete, the user is ready to begin the survey. Tap the SURVEY tab to access the

main survey tab.

There are 3 main areas to this screen. The middle largest area is for the widgets chosen by the

surveyor to display data.

1. Information Bar – Buttons for connecting/disconnecting the Hexcorder Pro from the

tablet, as well as for connecting a pipe locator

2. Survey Widgets – the survey widgets selected by the user appear in this area. Two can

be used at a time

3. Survey Information – this bar contains the survey start/pause button, access to the

survey layout widget screen, as well as survey name, date and time, chainage, and GPS

location information

Calculated Gradients

In DCVG modes, the user can select to view the DCVG values as separate ON/OFF values or as a

calculated gradient value, which automatically subtracts the ON value from the OFF value and

displays the difference as well as an estimated %IR. This difference is often more useful to the

surveyor.
