Use Purpose of STB Series

To measure the position of the reflection source, it’s essential to adjust the time axis.
This also involves calibrating the measurement range. For accurate echo height readings from the reflection source, fine-tuning the flaw detection sensitivity becomes crucial.
One must also conduct thorough inspections of the flaw detection equipment’s characteristics and performance, ensuring precise measurement of performance traits.
