VxAdmin generates files that may be used in most typical post-election audit processes.
For a ballot polling risk-limiting audit, no files are needed from the voting system.
For a traditional or batch comparison risk-limiting audit use the Tally Report Builder instructions, selecting the correct filter based on the units (precinct, scanner, batch, etc.) you're auditing.
For a ballot comparison risk-limiting audit or an image audit, cast vote records (CVRs) and image files can be pulled from the VxCentralScan and VxScan(s). Full file exports from VxAdmin will be available in a future software release. An imprinter can also be attached to a VxCentralScan to print a unique identifier on ballots scanned and the unique identifier can be found in the CVR. This allows for easier ballot retrieval and matching between CVRs, images, and ballots.
