Which of the following is critical to ensuring accurate results in Eddy Current Testing?

Calibrating the equipment is essential for achieving accurate results in Eddy Current Testing. Calibration ensures that the testing instruments are adjusted to a standard reference, minimizing measurement errors. This process involves comparing the output of the equipment against known standards or measurements and making necessary adjustments. In Eddy Current Testing, where subtle changes in electrical impedance can indicate material flaws, even small discrepancies can lead to misinterpretation of results. Therefore, regular calibration of the testing equipment helps maintain the reliability and accuracy of measurements, ensuring that any detected anomalies truly reflect the condition of the material being tested.
