What standard practice should be followed regarding equipment calibration in MPI?

Regular calibration of equipment in Magnetic Particle Inspection (MPI) is essential to ensure measurement accuracy and reliability. Calibration involves adjusting and verifying that equipment is operating within specified parameters, which is crucial in any inspection process.

In the context of MPI, the precision of magnetic fields, sensitivity of the particles, and the overall operational effectiveness directly affect the quality of inspections. If the equipment is not properly calibrated, it could lead to inaccurate readings which might result in undetected flaws or false indications, both of which can compromise safety and integrity.

Continuous calibration as part of a routine maintenance program helps identify potential issues before they impact operations, ensuring consistent performance. This proactive approach mitigates risks associated with equipment malfunction or drift over time and maintains compliance with industry standards.

The other options do not advocate for a systematic and preventive approach to calibration, which is why they fall short of establishing the best practice in maintaining the integrity and reliability of MPI equipment.
