1
Q
Calibrating the Time-Base
A
Using a reference block of known thickness and velocity of sound travel, the instrument will determine the sound velocity for the material needing to be inspected.
2
Q
Delay Control
A
Used to move signals on the baseline from left to right without changing relative pip distance. used to move distance travelled in wear plate of transducer, delay line or in water during immersion testing.
