During the surveying of a hole, the ‘DEPTH’ and ‘DEPTH INTERVAL’ can be changed between each survey point by selecting the desired textbox, followed by the keyboard icon and then entering the new values.
1315. Once the survey point has been recorded, move the RDI to the next depth interval and repeat steps 12 to 14 as necessary.16. When surveying is completed, disassemble the survey tool from the running gear and re-establish the link between the RDI and RC using the Infra-red window. Ensure there is direct line-of-sight between the RC and the RDI, before selecting the ‘Finish & Download’ button.NOTE: The current survey can be stopped and a new one started by selecting the ‘Finish & Start New’ button.All previous surveys including the current one are then available for download using the ‘Finish & Download’ button.

While viewing the survey data, the ‘SURVEY NAME’, ‘TOOL ID’ and the ‘# of SHOTS’ can be also viewed and confirmed at the top of the screen.
199. The expanded survey data also displays the battery status of the RDI when the shot was taken. A green battery indicates that the RDI battery is in good condition, as shown in the image on the right.A red battery indicates that the battery life of the RDI is close to, or has already reached, its minimum capacity for correct operation, and as a result survey readings may be inaccurate.At this stage replacement of the depleted battery with a fully charged RDI battery pack is recommended.WARNING: Data may be lost if surveys are not downloaded and the RDI battery is left to discharge. Also, if a new battery is not connected within 5 minutes of removing the flat battery, the RDI’s residual energy will be drained and data will be lost.

While Multi-shot surveys are distinguished by their names as well as by the time and date of the taken survey.Each survey will have both a CSV and XML file format. The CSV file can be opened using Microsoft Excel to view survey results, while the XML format is needed when importing the survey data into the RANGER SAS software for further survey analysis.7. To view survey data in excel format, double click the survey file with the correct CSV extension at the end of it. This will automatically open Microsoft Excel and display the survey data.
25During the transfer of files from the RC to the Flash Drive (USB STICK), a number of error messages may appear if correct conditions are not met during the file transfer process. These error messages will be triggered with the following actions:1. Attempting to copy a survey from the RC to a Flash Drive without the Flash Drive being connected to the RC.Make sure that the USB stick provided with the RC has been inserted into the correct slot (USB host) at the bottom of the RC boot, as shown to the right.
26During the transfer of files from the RC to the Flash Drive (USB STICK), a number of error messages may appear if correct conditions are not met during the file transfer process. These error messages will be triggered with the following actions:2.

27VITAL POINTS TO BE AWARE OF: BRASS BARREL HAS IDENTICAL THREADS AT EITHER END TO ENABLE IT TO BE REVERSED; THIS OPTIMISES ITS WORKING LIFE.Only use minimal amounts of a petroleum jelly or O-ring grease on O-rings and threads.Do not use pipe wrenches on brass barrel joints.O-rings have a dual function. In addition to their retaining action, they seal the barrel from ingress of drilling fluid. Continually check O-ring condition.Always use correct barrel size for your specific drilling conditions. If you’re in doubt about size to use contact your RANGER distributor.
