Ohio Revised Code Title XXXV. Elections § 3506.14

(1) Test and audit the variable codes applicable to that election to verify the accuracy of any computer program that will be used for tallying the ballot cards for each precinct in which an election will be held;

(2) Conduct systematic logic and accuracy testing of every component of every voting machine, marking device, or piece of automatic tabulating equipment with every ballot style to be used in the election to ascertain that the ballots are accurate and that the machines, devices, and equipment will accurately record, mark, or count the votes cast for all offices and on all questions and issues, as applicable. The test shall be conducted by processing a pre-audited group of ballots so marked as to record a predetermined number of valid votes for each candidate and on each question and issue, and shall include for each office one or more ballots that have votes in excess of the number allowed by law in order to test the ability of the automatic tabulating equipment to reject those votes. In that test a different number of valid votes shall be assigned to each candidate for an office, and for and against each question and issue. If an error is detected, the cause for the error shall be ascertained and corrected and an errorless count shall be made and certified to by the board before the count is started.
