In what condition should the eddy current instrument be before starting an inspection?

Checked for visual defects
Calibrated and functioning properly
Plugged into an artificial power source
In standby mode

The correct answer is: Calibrated and functioning properly

Before starting an inspection with an eddy current instrument, it is essential for the device to be calibrated and functioning properly. Calibration ensures that the instrument provides accurate and reliable measurements, essential for the integrity of the inspection. If the instrument is not calibrated correctly, it may lead to erroneous readings, which could compromise the assessment of the material's properties or the detection of flaws. Having the instrument in proper working condition also pertains to its operational readiness, which includes aspects such as battery levels, connection integrity, and software functionality. A well-calibrated and functioning eddy current instrument ensures that the inspector can trust the results obtained during the testing process. This is critical, particularly in applications where safety and compliance with standards are paramount.
