What must be ensured when calibrating ultrasonic testing equipment?

When calibrating ultrasonic testing equipment, it is essential that this process is performed according to detailed manufacturer specifications. Following the manufacturer’s guidelines ensures that the equipment is set up to function optimally and provides accurate and reliable test results. These specifications generally include specific standards for frequency, gain settings, and sensitivity levels that the equipment should achieve during calibration. By adhering to these detailed instructions, the operator can confirm that the testing equipment will perform as intended and meet industry standards for safety and quality assurance.

Calibration is a critical element of maintaining the integrity and reliability of ultrasonic tests. It should not be based solely on time intervals or previous usage, as environmental factors and equipment wear can affect performance. Regular calibration following the manufacturer's specifications helps in identifying any deviations early on, thus ensuring that the testing process remains effective and trustworthy.
