Which of the following is NOT a condition for RADAR evidence in court?

The statement that the operator graded the test is not a necessary condition for RADAR evidence in court. In the context of RADAR usage, the focus is primarily on the proper operation of the instrument and adherence to established procedures rather than the subjective assessment or grading of performance by the operator.

For RADAR evidence to be admissible, the operator must follow the correct procedures for operation, the RADAR instrument must be approved for use, and it must be calibrated accurately before use. These factors ensure reliability and accuracy in the readings obtained from the RADAR equipment, which is crucial for legal proceedings. Grading a test is not a formal requirement and does not contribute to the legitimacy or reliability of the RADAR evidence in the same way that the other conditions do.
